So I opened an earlier version of the large script and turned on cold folding, and tried to fold a rather long handler. Big mistake.
I need more specifics to begin working out what the problem might be. If Script Debugger crashed, then please send a crash report (you may have already done this as I’ve no checked the queue in a while). If there was a hang, then a Sample report would help. And, if you are able, please share the script that caused the problem (message me privately).
I’ll do that when I get home. It was a hang, and I believe it was reproducible. It’s a very simple script it does hundreds (thousands) of search replace in tagged text, so most of the lines are handler calls with three parameters.
