I want to open a modalpopup in frame.I pasted here my frame's htlm code and css style and This code works well with IE 7.0 but not with IE 6.0.In IE 6.0 i see scrollbars in my panel.What can cause this problem?How can i solve it?
I open frame in my main page by these width and height.
<cc1:modalpopupextender ID="mdlDelete" runat="server" PopupControlID="PnlFrameDelete" BackgroundCssClass="modalBackground" OkControlID="btnDeleteOk" CancelControlID="btnDeleteCancel" TargetControlID="btnDelete" > 
</cc1:modalpopupextender><asp:Panel ID="PnlFrameDelete" runat="server" style="display:none">
 <iframe id="deletefrm" frameborder="0" src="../Frame/deletefrm.aspx" height="98px" width="342px" > </iframe> <div> <asp:Button ID="btnDeleteOk" runat="server" Text="Yes" Width="40px" style="display:none" /> <input id="btnDeleteCancel" type="button" value="No" style="width:20px;display:none" /> </div> </asp:Panel>
<body style="margin: 0px;">
This is the frame's aspx:
<form id="form1" runat="server"> 
<asp:ScriptManager ID="ScriptManager1" runat="server" /> <asp:Panel ID="pnlDelete" runat="server" CssClass="modal-dialog"> <div class="container"> <div class="header"> 
 <div class="msg">Warning</div> <asp:LinkButton ID="LinkButton1" runat="server" CssClass="close" OnClientClick="$find('mdlDelete').hide(); return false;" /> </div><div class="body"> <h2><asp:Label ID="lblMsg" runat="server" Text="Are u sure?"></asp:Label></h2> </div> <div class="footer"> <div class="right"> 
 <asp:Button ID="btnDeleteOk" runat="server" Text="Yes" Width="40px" OnClientClick="okay();" /> <input id="btnDeleteCancel" type="button" value="No" onclick="cancel();" style="width:40px" /> </div> </div> </div> </asp:Panel> </form>
And this is the CSS:
/* dialog frame */
.modal-dialog
{
    position:absolute;
    margin:auto;
    height:98px;
}
/* dialog contents container */
.modal-dialog .container

    border:solid 1px #99aabd;
    background-color:#F2F9FF;
    padding: 0px 0px 0px 0px;
} 
/* dialog header */
.modal-dialog .header
{
    background:url(../images/sprite.gif) repeat-x 0px -1100px;  
    height:20px;
    padding-top:5px;
}
/* dialog header message */
.modal-dialog .header .msg
{
    vertical-align:middle;

    background: url(../images/icons.gif) no-repeat -732px 0px;
