If your builds are going smoothly you don't have to change anything. Try 
it in LC 9 and see. The problem only occurs if any "open" or "close" 
handlers do something that interferes or throws errors.

A "can't find stack" used to occur the first time you build during any 
one session. The updated handler check fixes this so you don't need to 
worry about it any more.

The idea is that this fix will prevent the handler from executing at 
all, so it needs to be at the very front of the handler, right after the 
"on <handlername>" line.

Yes, that's what the additional lines do -- exit the handler before it 
can run. And I agree that this is an issue for some apps. The problem it 
tries to solve is retention of script local variable values, as well as 
preventing unnecessary handlers from running. But I'd rather 
reinitialize things when necessary than to add extra lines to so many 
engine messages.

I'd be happy with a simple toggle that lets me turn on lockmessages 
before building. I've been accomodating that behavior for years.
