Modal Popup Vert Scrollbar not working in Firefox (OK in IE)

Posted By:      Posted Date: October 24, 2010    Points: 0   Category :ASP.Net

I am having a problem with a modal popup that has a vertical scroll bar.  In IE the vertical scroll bar works as it should.  However in Firefox, if I try to click and drag the scroll box or "thumb" along the track the whole modal popup is draged accross the screen.  The scroll buttons will advance the scroll, I just can't grab the tumb without dragging the whole screen.

Any suggestions on how to fix this?

The popup text is in a div with the following properties:

<div style="height: 465px; width: 742px; overflow-y: scroll; overflow-x: hidden;
float: left;"

Modal Popup Not Working...


I've looked at every problem associated with the Modal Popup Extender to no avail. I'm using Visual Studio 2008 with the latest Ajax Toolkit. And I've tested it on all the major browsers and it doesn't work on any. I've poured over numerous examples and they all look like mine but it still doesn't work. As of right now, everything is running on my local host. I do have a script manager as well because in this snippet it doesn't show it. All I want to do is to show the panel with some text in it. So it isn't super fancy. All that happens when you click the link button is a page submission. Also, after I click on the link button I get the "Confirm Page Resubmission?" alert when ever I refresh the page to test new code. Here is the code. Thanks in advance.

<div class="DivInMidRight">
<asp:LinkButton runat="server"  CausesValidation="false" ID="SkillsBtn" CssClass="LinkBtn" onmouseover="tooltip.show('Click for Detailed Information.');"   onmouseout="tooltip.hide();">Skills & Experience:</asp:LinkButton>
<asp:ModalPopupExtender BackgroundCssClass="ModalPop" TargetControlID="SkillsBtn" PopupControlID="SkillsPnl" DropShadow="true" CancelControlID=

CSS font is working in FireFox but not in Internet Explorer 8.0

Hi All, I tried a lot but I could not figure out why the IE is not taking font size and name in to effect from CSS. In firefox my website could be seen very nice but in IE it is little bit unshiny and font size is bigger For the difference which I am talking about could be seen  if your PC have both firefox and IE installed. Please go to http://www.nymidtowndentistry.com open it in FF and IE and you could see the font and alignment related change. All these settings are in body element of CSS. Do you any idea regarding this? Any help would be appreciated. Thanks for your time. -Hitesh
