When should cmd-period work?

Hi Jacque,

This has happened to me several times in Rev 3.0, but I've never been  
able to pin it down to a recipe. It's almost like what happens when a  
running script throws an error and kicks you into debug mode, and you  
try to do things with the interface, but nothing works. Then you  
notice the error message and slap yourself in the forehead and say to  
yourself "What a dork!", then click the stop button in the script  
editor to get out of debug mode, and everything's fine. But when this  
happens you can't find anything to click, and you want to slap your  
computer instead. Cmd-period doesn't work because the script is  
already interrupted. It's almost like you really are in debug mode but  
the interface hasn't been updated to reflect that. Like you, I seem to  
notice it happen when handlers are calling handlers are calling  
handlers, in different objects.

It's very frustrating; maybe if we compare notes we can come up with a  
reliable recipe for reproducing it.
