Some of the exceptions should be fixed now. I am using the WebGUI WorkspaceTabs control now instead of the Windows TabControl. I am assuming (and I'm sure it is) that the WorkspaceTabs control behaves much better in the web site than the Windows native control (or else why would you have it)?
As far as FCKeditor, I am looking at using the Winthusiasm HTML Editor for ASP.NET Ajax. This is a lightweight easy deployment editor with all resources residing in a single DLL. I hope this might be an excellent alternative to everyone who is complaining about FCKeditor.
The links are:
This looks really promising, the most apparent feature that it lacks is support for tables, but has the basic features that I think most people are looking for.
If I am successful implementing it, I will create a thread in the FCKeditor forum about it.
