Too much code to condense down to a simple example. Perhaps that is part of my problem.

 

I did just try removing all of the control validators from the page, and the problem went away. It could be a problem with Firefox and Validators. I don't know what CuteEditor's Visible state would have to do with anything, though.

 

Last year there was quite a bit of chit-chat on the boards about new unresponsive script errors that a lot of sites were observing with Firefox. The solution was always to increase the dom.max_script_run_time from 5 to 10 seconds. I tried increasing it to 30, and that didn't help. So I think I am getting into a loop or something.

 

Anyway, thanks for your interest. If I can find a useful, simple example I'll share it with you and the forum.
