Created Issue: Not Compatible with IIS 8 [27358]

Just let me know what else to try to prove this false.

Steps:
Built fresh ASP form apps using VS 2012 Express for Web.
Added the toolkit using NuGet.
Created an AJAX toolbox tab and browsed to the toolkit dll to add the controls.
Added the following to the asp:Content section:
```
<ajaxToolkit:TabContainer ID="tc1" runat="server" ActiveTabIndex="0">
<ajaxToolkit:TabPanel ID="TP1" runat="server">
<HeaderTemplate>
Test 1
</HeaderTemplate>
<ContentTemplate>
content 1
</ContentTemplate>

</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel ID="TP2" runat="server">
<HeaderTemplate>
Test 2
</HeaderTemplate>
<ContentTemplate>
content 2
</ContentTemplate>

</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>
```
Ran locally and the tab control was present and working.
Uploaded to site.
The tab control was not showing with the busy cursor present.
Thanks,
Alan
