Just added the following ASCX to an existing module project...

<% @ Control Language="vb" CodeBehind="Slider.ascx.vb" Inherits="GCS.Modules.AutoInventory.Slider" TargetSchema="http://schemas.microsoft.com/intellisense/ie3-2nav3-0" %>
<%@ Register TagPrefix="radr" Namespace="Telerik.WebControls" Assembly="RadRotator.Net2" %>

<radR:RadRotator id="rdScrll5" runat="server" FrameTimeout="4000" pause ="true" width="140" height="100" >
 <FrameTemplate>

   <a href="<%# DataBinder.Eval(Container.DataItem, "URL") %>"><img border="0" src="<%# DataBinder.Eval(Container.DataItem, "ImageURL") %>" alt="" /></a>

 </FrameTemplate>

 </radR:RadRotator>

 <img id="radRotator_prev" runat="server" src="/images/lt.gif" title="Previous Image" alt="Previous Image" style="border:0px; float: left;" class="navigationBtn"/>

 <img id="radRotator_next" runat="server" src="/images/rt.gif" title="Next Image" alt="Next Image" style="border:0px; float: right;" class="navigationBtn" />

Did not need to add reference to Telerik.Web.UI for it was already in use...

DID ADD reference to RadRotator.net2

Compiles and functions just fine on Development machine...

I recieve "Circular file references are not allowed" from Testing DNN site - of course this is during JIT and I have no info on where this is occuring.  I have checked using nDepends and a few other such tools.  No Circular references are reported expect on Testing Server???

Any help would be greatly appreciated...
