Version? CuteEditor_for_Net5
Example? The problem does not reproduce in the Multiple.aspx sample. The sample is very slow in Firefox, but does not show the unresponsive script error.
I am trying to strip away layers of code to find out whether the problem is occurring in CuteEditor or in my application layer. The problem occurs during a WebForm postback owned by a Button control that I have added. It may have nothing to do with CuteEditor. I'll let you know if my opinion changes.
Thanks for the response.
