THOMAS, Chief Justice.
This appeal is taken from a judgment of the district court affirming a conviction by a jury in county court of the offense of reckless endangering which is proscribed in § 6-2-504(b) and (c), W.S.1977.1 The questions presented relate to the granting of a motion in limine which prevented the defendant from referring to the fact that one of the State’s witnesses had been arrested in connection with the events underlying the offense of which the defendant was convicted; the failure to grant a mistrial because of the lack of compliance by the State with a discovery order; asserted prosecutorial misconduct claimed to be so prejudicial as to deprive the defendant of a fair trial; and the manner in which the trial was conducted which is claimed to be deprivation of due process. This latter contention ties to the claim of prosecutorial misconduct additional assertions relating to jury misconduct; an inopportune break for a lunch recess; and assistance of the trial court with respect to prosecutorial evidence which manifests bias. We can discern no prejudicial error with respect to any of the claims made by appellant, and we affirm the judgment of the district court affirming the conviction in the county court.
As we have noted, Delphine Lindsey was charged with a violation of § 6-2-504(b) and (c), W.S.1977. Following a verdict of guilty returned by a jury in the county court, she was sentenced to serve a term of 30 days in the county jail, of which 29 days were suspended, and she was placed on six [651]*651months unsupervised probation. An appeal then was taken to the district court, and in connection with that appeal a statement of the case, as provided by Rule 4.07, W.R.A. P.C.L.J., was prepared.2 This rule assumes that the statement of the case shall become the record on appeal to the district court in lieu of the usual documents and recordings. There were some special aspects of this statement of the case, however.
In the statement of the case itself this language appears:
“Neither these points nor the statement of the case are meant to be exclusive of the audio transcript of the proceedings, exhibits, and other matters contained in the court file.”
The order approving the statement of the case entered by the judge in the county court says in part:
“A WRITTEN STATEMENT OF THE CASE having been presented to this Court by the defendant and the State of Wyoming, and the Court having reviewed the same and being satisfied of the truthfulness thereof, and being otherwise fully advised;
“IT IS HEREBY ORDERED that, pursuant to Rule 4.07, W.R.A.P.C.L.J., the Statement of the Case filed herein is approved and shall be made part of the Record on Appeal, together with the court file, exhibits, and audio transcript of the proceedings in the lower court.” (Emphasis added.)
There also was included on the face of the order a handwritten note by the county court judge stating: “The Court calls specific attention to the Audio Record of the proceedings & the matters reflected thereon.” Upon review the district court affirmed the judgment and sentence entered in the county court, and this appeal is taken from the order of the district court affirming the conviction.
In her brief Delphine Lindsey recites these issues for resolution:
“I. Whether it was error to grant the Motion in Limine preventing the Defense from referring to the fact that Koenig was arrested for impersonating an officer.
“II. Whether the Court erred in refusing to grant a mistrial based on the failure of the State to comply with the discovery order.
“III. Whether the prosecutorial misconduct was so prejudicial as to deny Appellant a fair trial.
“IV. Whether the trial was conducted in a manner inconsistent with due process.”
The State of Wyoming states the issues to be:
“I. Did the trial court err in granting the State’s Motion in Limine preventing appellant from referring to any charges which may have been filed against Mark Koenig, a witness in this case?
“II. Did the trial court err in its handling of appellant’s complaints regarding discovery?
“HI. Was appellant deprived of a fair trial by prosecutorial misconduct or the conduct of the trial court?”
In her reply brief, Delphine Lindsey presents an additional issue:
“Whether the tapes are superseded by the Statement of the Case pursuant to Rule 4.07 W.R.A.P.C.L.J.”
[652]*652As a preliminary matter we will address the scope of the record to be reviewed. Lindsey contends that the electronic tapes of the proceedings in the county court cannot be considered in this appeal because they were superseded by the statement of the case included in the record on appeal. Although Lindsey does not present this contention we also note that, in accordance with Rule 4.02, W.R.A.P., the failure to transcribe the tape recordings would be a ground for not considering them.3 Rule 4.02, W.R.A.P., differs from Rule 4.02(b), W.R.A.P.C.L.J., which provides that the electronic tapes need not be transcribed for the appeal to the district court, unless that court so requires. We already have alluded to those portions of the record which manifest the intent of the trial court that the record in this instance not be limited to the statement of the case.
It has been a long-standing policy of this court that the record on appeal should include a proper transcript of the proceedings in the trial court, and in the absence of a properly certified transcript of those proceedings this court will not consider them. Salt River Enterprises v. Heiner, Wyo., 663 P.2d 518, 520 (1983), citing Roy v. Union Mercantile Company, 3 Wyo. 417, 26 P. 996 (1891); In re Basin State Bank, 43 Wyo. 1, 296 P. 1074 (1931); Northwestern Terra Cotta Company v. Smith-Turner Hotel Company, 47 Wyo. 190, 33 P.2d 915 (1934). An alternative to a transcript is recognized in Rule 4.03, W.R.A.P., which permits the appellant to prepare a statement of the evidence, to be approved by the district court in those instances in which a transcript is unavailable. Delphine Lindsey did not pursue that alternative for a transcript in this case.
In this court adverse consequences have attached to the failure to provide a statement of the case where no transcript is available. Minnehoma Financial Company v. Pauli, Wyo., 565 P.2d 835 (1977). In Wydisco, Inc. v. McMahon, Wyo., 520 P.2d 218 (1974), the appeal was dismissed because neither a transcript nor a statement of the case was furnished, and the court concluded that it was unable to consider the questions raised in the absence of one or the other. In another case the court said it would presume the regularity of the proceedings and limit itself to questions which did not require a review of the transcript. Matter of Manning’s Estate, Wyo., 646 P.2d 175 (1982). In Salt River Enterprises v. Heiner, supra, the court advised that in the absence of a proper transcript the trial court’s findings of fact would be accepted for purposes of the appeal. In Scherling v. Kilgore, Wyo., 599 P.2d 1352 (1979), the consequence of the appellant’s failure to avail himself of Rule 4.03 was that he could not sustain his burden of demonstrating error in the appeal.
Despite the possibility that this court could limit or refuse review in the absence of an appropriate record in the form of a statement of the case according to our rules of appellate procedure or a transcript, we have, in the interest of justice, examined the record including the tapes and considered each of Delphine Lindsey’s claims on the merits. Lindsey conceded in oral argument that the statement of the case that was offered was not as thorough as it might have been, although obviously she assumed that it could meet the requirements of Rule 4.03 W.R. A.P. We do not intend to recede from our rule that a transcript rather than the electronic recordings should be provided in this [653]*653court if claims of error are asserted based upon matters in the record and no statement of the case has been prepared in accordance with Rule 4.03, W.R.A.P. In this instance the record as manifested by the electronic tapes is essentially consistent with the statement of the case. The tapes do reflect some details of significant factual matters. We therefore have relied upon both sources to resolve the issues.
We have gleaned the material facts from the record items alluded to previously. Delphine Lindsey lived in an apartment on the third floor of an apartment building, and her daughter and grandson lived in an apartment across the hall. A dispatcher for the Casper Police Department also lived on the third floor of the same building. On June 24, 1984, Sally, a female friend of the police dispatcher went to the apartment to water plants. Sally was accompanied by two friends, Mark Koenig and Matt. Del-phine Lindsey was home, but her daughter and husband were out for the evening. The grandson with a friend, Michael, was in and out of Delphine Lindsey’s apartment and his mother’s apartment.
Koenig went with Sally while she watered her friend’s plants, but Matt entered into dialogue with Delphine’s grandson and his friend in the hallway. Koenig then joined in this dialogue which apparently became a confrontation and then degenerated into an altercation involving pushing and shoving. At that time Koenig displayed a dispatcher’s badge which he had taken from the apartment, and Koenig and Matt then took a set of numchucks away from the two boys. (Numchucks are two wooden handles which are joined by a short piece of chain, and which have no apparent utility other than as an offensive or defensive weapon.) At that juncture the grandson came to Delphine Lindsey for assistance. He told her that two men had his friend up against the wall. Delphine Lindsey then obtained her Smith & Wesson .32 caliber pistol and sent the grandson to his own apartment to obtain his mother’s cordless phone in order to call the police. At about the same time Sally, who had finished watering the plants, left her friend’s apartment, walked down the hall and started down the stairs. Koenig and Matt then left the grandson’s friend and followed her. When they reached the parking lot the men threw the numchucks into a nearby field or yard.
Delphine Lindsey managed to telephone the police on the cordless phone as she was following Sally, Koenig and Matt down the stairs. She then confronted these three people in the parking lot and, with her pistol in her hand, she ordered them to find the numchucks. She restrained Sally and Koenig while Matt went to the field and retrieved the numchucks. Delphine Lindsey refused to put her gun down even though she was asked to by Koenig who again displayed the police dispatcher’s badge.
Three officers then responded to the call by Delphine Lindsey. While they were talking to the participants Lindsey’s daughter and son-in-law arrived at the parking lot. They were alarmed by witnessing the police with Lindsey and their son, and they also became involved in the situation. After some time the police officers took all these people with them to the police station for the purpose of obtaining statements. The only person arrested that evening was Koenig who was charged with impersonating an officer. (It appears that charge was dropped at some later time, and he was charged with unlawful entry.) Some two months later Delphine Lindsey was served with a criminal complaint charging the reckless endangering offense.
The State of Wyoming filed a motion in limine to prohibit any mention of the charges against Koenig at the trial of Del-phine Lindsey, and the court granted the State’s motion. While no mention was made of the charge against Koenig the county court permitted both the State and Delphine Lindsey to develop completely the facts leading up to the incident involving the charge of reckless endangering. The tape recordings of the trial proceedings demonstrate that both parties took advantage of this opportunity. On appeal, how[654]*654ever, Delphine Lindsey contends that her inability to bring out the fact that it was Mark Koenig who was perceived as the wrongdoer by the police on the night of the incident prejudiced her defense. Her claim of relevance with respect to Koenig’s arrest is:
“ * * * Clearly it is of consequence to know if Appellant was chasing after a police officer or not. If Mr. Koenig were not a police officer, as he was not, but merely impersonating one, then the reasonableness of Appellant’s actions is much more apparent.”
There is no question that the evidence before the jury demonstrated that Koenig had displayed an officer’s badge and that he was not an officer. The fact that he was arrested and charged would not have aided the jury in understanding that aspect of the case. Certainly it would not justify the conduct of Delphine Lindsey. It would not serve in any way to demonstrate that her conduct in pointing the firearm at Sally, Matt and Koenig was “reasonably necessary in defense of [her] person, property or abode or to prevent serious bodily injury to another.” For that reason the failure to present the information to the jury could not have prejudiced her right to a fair trial.
The admission of evidence is left to the sound discretion of the trial court. Stogner v. State, Wyo., 674 P.2d 1298 (1984); City of Evanston v. Whirl Inn, Inc., Wyo., 647 P.2d 1378 (1982); Hopkinson v. State, Wyo., 632 P.2d 79 (1981), cert. denied, 455 U.S. 922, 102 S.Ct. 1280, 71 L.Ed.2d 463 (1982); Canyon View Ranch v. Basin Electric Power Corporation, Wyo., 628 P.2d 530 (1981); Barnard v. Wendling, Wyo., 627 P.2d 603 (1981); Hayes v. State, Wyo., 599 P.2d 569 (1979); Boggs v. State, Wyo., 589 P.2d 839 (1979); Peterson v. State, Wyo., 586 P.2d 144 (1978); Daellenbach v. State, Wyo., 562 P.2d 679 (1977). The trial court may exclude inadmissible evidence upon a motion in limine. Hayes v. State, supra. Rule 402, W.R.E., provides in pertinent part that, “ * * * [E]vidence * * * which is not relevant is not admissible.” Rule 401, W.R.E., defines “relevant evidence” as follows:
“ ‘Relevant evidence’ means evidence having any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence.”
Delphine Lindsey has not explained how the evidence of charges against Koenig would make the existence of any fact of consequence to the determination of the charge against her more or less probable, and the court has not been able to divine any such purpose. No reversible error occurred in excluding, pursuant to the motion in limine, reference to the arrest or charges against the witness Koenig.
The discovery order upon which Delphine Lindsey relies in connection with her second claim of error provided that the State must furnish:
“ * * * [A]ll information of whatever form, source or nature within the possession of the Natrona County District Attorney, or any State or Federal Law Enforcement Agents known to the Natrona County District Attorney, and all information subject to his knowledge with reasonable diligence * * * which may lead to evidence which may be or become of benefit to the Defendant preparing for or presenting the merits of his defense * * *."
During the cross-examination of a police officer, after the State had produced most of its witnesses on the first day of trial, Delphine Lindsey’s attorney discovered that the officer had made a report which had not been provided to the defense. Defense counsel promptly moved for a mistrial. The discussion of this matter then continued in chambers, and it became apparent that another police report and a statement of one witness, both relevant to the case, had not been provided to the defense. Defense counsel then renewed the motion for a mistrial; requested that the State’s witnesses’ testimony be stricken; refused to agree to a partial striking of the testimony; and asked for a continuance [655]*655of the trial. In addition counsel moved for a contempt citation against the prosecutor.
The county court judge admonished the prosecutor; ordered that the undisclosed documents be made available to defense counsel; denied the motion for mistrial; granted a continuance until the following morning but denied any additional continuance; took the matter of contempt under advisement; and granted leave to the defense to recall the officer who had made the second undisclosed report and the witness whose statement had not been furnished. Rule 14, W.R.Cr.P.C.C., is identical with Rule 18, W.R.Cr.P., and it provides in pertinent part:
“If, at any time during the course of the proceedings, it is brought to the attention of the court that a party has failed to comply with this rule, or with an order issued pursuant to this rule, the court may order such party to permit discovery or inspection of materials not previously disclosed, grant a continuance, or prohibit the party from introducing in evidence the material not disclosed, or enter such other order as it deems just under the circumstances.” Rule 14(h), W.R.Cr.P. C.C.
On several occasions the court has construed the provisions of Rule 18(h), W.R. Cr.P. We have articulated a preference for the relief provided by Rule 18(h), W.R. Cr.P., and have said that it “must be sought by an aggrieved defendant, and it is impermissible to by-pass that relief and seek a mistrial. Simms v. State, Wyo., 492 P.2d 516, [524] (1972).” Nimmo v. State, Wyo., 607 P.2d 344, 348 (1980).
The discretion of the trial court in dealing with a breach of any discovery order has been recognized. Stogner v. State, supra; Nimmo v. State, supra; Sims v. State, Wyo., 530 P.2d 1176 (1975). The decision of the court in addressing the breach of a discovery order will be set aside only for an abuse of discretion. Nimmo v. State, supra; Dodge v. State, Wyo., 562 P.2d 303 (1977). In this regard the burden is upon the defendant to specify the evidence that might have been available to him to rebut the undisclosed information if more time had been available. Stogner v. State, supra. We have refused to afford any relief if the appellant could not specify what helpful evidence he might have produced. Siegert v. State, Wyo., 634 P.2d 323 (1981). There is no question that the harmless error concept will be applied to such claims. Nimmo v. State, supra, citing Nimmo v. State, Wyo., 603 P.2d 386 (1979). In this case the county court granted the inspection sought by the defense counsel and a short continuance. The offer of the county court to strike portions of the testimony of the State’s witnesses was refused.
This case may be additionally illustrative of the danger of reliance upon an open file policy. In Siegert v. State, supra, the open file policy was applauded. The failure to comply with a discovery order is to be deplored. This record indicates, however, that the prosecutor was as surprised to learn of the two police reports alluded to in the testimony of the witness as the defense was. These documents were in Koe-nig’s police file, and were not in the Del-phine Lindsey file. Nothing indicates that any breach of the discovery order in this instance was willful. Under the circumstances the granting of a continuance is within the sound discretion of the trial court. Capshaw v. State, Wyo., 714 P.2d 349 (1986); Siegert v. State, supra; Irvin v. State, Wyo., 584 P.2d 1068 (1978); Robinson v. State, 18 Wyo. 216, 106 P. 24 (1910). The extent of relief in the form of a continuance is also within the discretion of the trial court.
Delphine Lindsey has not demonstrated with any degree of specificity how she was prejudiced by the order of the county court in treating with the breach of the discovery order. She explains, “[h]owever, prejudice is often difficult to show.” That is not a proper method of carrying the burden of demonstrating prejudice. We are unable to independently discern any reason to upset, the verdict in this case in the absence of any specific explanation of prejudice to the appellant.
[656]*656Delphine Lindsey next urges prosecutorial misconduct deemed to be so prejudicial as to have denied her a fair trial. She relies upon the failure to comply with the discovery order, which contention has previously been dealt with. In addition she points to the exhibition of a second pair of numchucks and the repeated use of leading questions on direct examination by the prosecutor. We have decided that there was no error with respect to the failure to comply with the discovery order which was not cured by the relief granted by the district court.
Turning then to the other matters, the prosecutor, in the course of the cross-examination of Lindsey’s grandson, showed the grandson the numchucks taken from him by Koenig and Matt which had been admitted as State’s Exhibit 1. The grandson agreed that his numchucks did have a chain on them when the men took them away from him, and no chain was on them at the time of trial. The examination then continued in this way:
“Mr. Hruby: In fact [shuffle of paper bag, rattle of chain], with a chain on ’em, they look something like this, right?
“Merritt: Right.
“Hruby: That correct?
“Merritt: Right.
“Raymond: Objection. This isn’t a show of martial arts, your honor. I’d ask that those be put away. We have an exhibit. I don’t know what’s going on here.
“Hruby: We have an exhibit without a chain and the witness has stated they look something like this with the chain on them.
“The Court: Fair, let’s proceed.”
The second set of numchucks were not then offered into evidence nor did the prosecutor make any further reference to them. No error occurred in permitting the use of this second set of numchucks for illustrative purposes.
With respect to excessive use of leading questions by the prosecutor we do not perceive from perusing the record and listening to the electronic tapes that this in fact occurred. In any event the scope and manner of the examination of witnesses is committed to the control of the trial court. Rule 611, W.R.E. No error in this record in this regard is demonstrated by the record.
The rule is well established that in considering a claim of prosecutorial misconduct the court reviews the entire record to determine if there was the denial of a fair trial. Sanchez v. State, Wyo., 694 P.2d 726 (1985); Wheeler v. State, Wyo., 691 P.2d 599 (1984); Stogner v. State, supra, 674 P.2d at 1302; Freeze v. State, Wyo., 662 P.2d 415 (1983); Jones v. State, Wyo., 580 P.2d 1150 (1978). Appropriate objections to the misconduct and subsequent curative instructions by a trial court may cure any error. Mayer v. State, Wyo., 618 P.2d 127 (1980); Six Feathers v. State, Wyo., 611 P.2d 857 (1980); Simms v. State, supra. We only reverse for prosecutorial misconduct if it results in substantial prejudice. Peterson v. State, supra; Hays v. State, Wyo., 522 P.2d 1004 (1974).
In Hopkinson v. State, supra, 632 P.2d at 166, and Freeze v. State, supra, 662 P.2d at 419, we quoted from the Supreme Court of the United States:
“Prosecutors cannot and should not be muzzled. It must be kept in mind that the prosecuting attorney is a representative of the State whose obligation is to govern impartially, whose aim is not that it win a case but that justice be done. It is his mission that guilt shall not escape or innocence suffer. He is duty bound to prosecute with earnestness and vigor. While he may strike hard blows, he is not free to strike foul ones. Singer v. United States, 1965, 380 U.S. 24, 85 S.Ct. 783, 791, 13 L.Ed.2d 630; Berger v. United States, 1935, 295 U.S. 78, 55 S.Ct. 629, 633, 79 L.Ed.2d 1314.”
It is the prosecutor’s duty to seek justice, not necessarily a conviction. Jeschke v. State, Wyo., 642 P.2d 1298 (1982); Hoover v. State, Wyo., 641 P.2d 1263 (1982); Valerio v. State, Wyo., 527 P.2d 154 (1974). Even so a duty is imposed upon the defense to object to improper comment in order [657]*657that the trial court may have an opportunity to remedy the situation. Wheeler v. State, supra; Goodman v. State, Wyo., 601 P.2d 178 (1979).
In Browder v. State, Wyo., 639 P.2d 889 (1982), we did accumulate matters such as this and conclude that in a very close case the fairness of the trial was called into question. In this instance, however, two of the acts of the prosecutor which are relied upon were not misconduct. There is nothing to accumulate. Capshaw v. State, supra. With respect to the discovery order matter prosecutorial misconduct results in a reversal only if there is substantial prejudice. Peterson v. State, Wyo., supra, Hays v. State, supra. That prejudice must be identified with sufficient particularity. Peterson v. State, supra. What we have said above with respect to the failure to make discovery controls the prejudice aspect of that one claim of prosecutorial misconduct. The Constitution guarantees only a fair trial. No demand is present that any trial be perfect. Peterson v. State, supra. The appellant has failed to persuade this court that any conduct of the prosecutor denied her a fair trial.
We then address the matters relating to Delphine Lindsey’s final claim. The record discloses that there were two occasions of impropriety during the deliberations of the jury. Three jurors telephoned family members to advise them that the jurors would not be home for supper. When this was discovered the county court judge called each of the jurors involved from the jury room, administered an oath to the juror, and asked if the juror had used the telephone, whom the juror had telephoned, whether the juror discussed the case, and whether the conversation influenced the juror’s deliberations in any way. All three jurors answered that they had not spoken of the case nor had the conversation influenced their deliberations. The county court then found that although the conversations were improper nothing had occurred that contaminated the jury.
The second problem with respect to the jury relates to the relief for approximately 30 minutes of the deputy sheriff who had been properly sworn as the bailiff by another deputy sheriff who had not been sworn as a bailiff. The first sheriff did properly instruct the second sheriff, and it was only when the jurors asked if they might review part of the testimony and thé unsworn bailiff telephoned the judge to inquire about the jurors’ request that this discrepancy was discovered. In this instance also the county court judge promptly administered an oath to the second deputy sheriff and inquired of him what had transpired during the time he served as bailiff over the jury. The deputy sheriff testified that two jurors had come out to call; that he had dialed the numbers for them; and that he stood nearby and overheard their end of the conversations in which their family members were informed that the jurors would not be home for dinner. The sheriff also testified that one of the jurors had come out to inquire about reviewing the testimony; that he had then called the judge; and that thereafter a different juror came out to say they had changed their minds about reviewing the testimony. In this instance the county court judge also found that this occurrence had not contaminated the jury. In both instances an opportunity was afforded to the defense and the prosecution to question the jurors and the deputy sheriff. Both attorneys declined to do so.
The burden is on the defendant to demonstrate prejudice resulting from the ruling of a trial court on a motion for mistrial based on jury misconduct. Searles v. State, Wyo., 589 P.2d 386 (1979); Roby v. State, Wyo., 587 P.2d 641 (1978); Dobbins v. State, Wyo., 483 P.2d 255 (1971). In Drummer v. State, Wyo., 366 P.2d 20, 26 (1961), this court quoted with approval the following language from Trombley v. State, 167 Ind. 231, 78 N.E. 976, 977 (1906):
“We are justified in disturbing a verdict of guilty on account of the alleged misconduct of a juror only when it is shown that such misconduct was prejudicial to the rights of the defendant, or when such a state of facts is shown that it may [658]*658fairly be presumed therefrom that the defendant’s rights were prejudiced. * * ”
In a civil case in which juror misconduct was alleged as a ground for reversal we held that not only must prejudice be demonstrated to arise from the misconduct, but that this court defers to the trial judge with respect to a finding of prejudice. Distad v. Cubin, Wyo., 633 P.2d 167 (1981). In the case of Delphine Lindsey the county court judge found no prejudice to her from the improprieties alleged. Delphine Lindsey has not demonstrated that the trial judge abused his discretion in this regard. Distad v. Cubin, supra.
Finally, Delphine Lindsey contends that the trial court decided to take a lunch break at “what Appellant felt to be a crucial point in the cross-examination” of the victim. She contends that she was denied due process. She does concede that people do need to eat and that an objection already had interrupted the on-going flow of the cross-examination. Delphine Lindsey also complains that the trial court assisted the prosecutor in getting a statement into evidence and urges that this assistance manifests bias on the part of the trial court in favor of the prosecution. In the context of the entire proceedings the one instance is not sufficient to demonstrate bias in favor of the prosecution. Neither of these matters can be perceived as reversible error.
We conclude that there was no reversible error based on any of the issues raised by Delphine Lindsey. The order of the district court affirming the judgment and sentence entered in the county court is affirmed.
