Adam,
I have an application with CEv6 in VS2005 SP1 and SO XP SP1 with IIS 5 and IE 6, and I had implemented some UserControls using CE!
I had have some problems when I try to show the control, the webform doesn't responde!
I tested the samples implemented by yours and the results are the same!, (C:\Desarrollo\CuteEditor\CuteEditor_for_NET6\Framework 2.0\vb) and these are the steps!
1. The proyect! (CE in develop is showed correctly)
2. Running the project! (Problem procesing the default page in VB)
3. if I remove the follow tag:
<CE:Editor id="Editor1" EditorWysiwygModeCss="../example.css" runat="server" ></CE:Editor><br />
the page is called correctly!
I checked with the demo license and with my license but in both cases the result was the same!. The process doesn't present an error to catch and follow the trace!
I checked the framework 1.x sample but it works correctly!
I appreciate the help that you can provide me!
