Hi Tim,
I tried to reproduce the reported problem locally, but to no avail. Could you please verify that you have Telerik.Web.UI.WebResource.axd handler registered in the web.config?
If you do have the above handler registered, could you please open a formal support ticket and provide a sample fully runnable project and / or a live URL reproducing the problem so we can investigate it further?
All the best,
Dobromir
