Piece of cake in System 7 (Process Manager and AppleEvents), very 
difficult in System 6.0.x and earlier. Older and wiser heads may correct 
me, but I wouldn't want to tackle this in System 6.0.x; it would be *very* 
kludgy and would probably break every time you looked at it cross-eyed. 
And any solution that worked in 6.0.x would fail under System 7.

A note to the nervous: I know a lot of us are still running System 6.0.x 
and earlier, and will be for a long time. I'm not recommending that such 
folks be abandoned or forgotten. It's just a fact that some things that 
are hard to do in 6.0.x (and impossible to do in a clean, supported 
fashion) are simple in 7.0. If it weren't so, we wouldn't have built 
System 7!

Hope this helps.
