Adam - Do you have any comments on this?  Seems that UpdatePanels should not cause this error.  I have UpdatePanels as well, but not on the editor.

 

Actually, I don't have any UpdatePanels on the page this is occuring.  I have a couple frames with update panels in them, but not the actual page.   I have the Cute Editor inside a <formview>, but no UpdatePanels.

 

Any ideas?
