I can't remember all the interactions but the trouble I am thinking is  
that what if someone is writing an application that does some  
background stuff (like animating) and if there is something in the  
interactor that is constantly bringing the window to the front that is  
going to be a bit annoying.

   I have no idea if that is going to happen or not but it seems  
awfully likely. Then again, my patch/hack may have just been skirting  
the issue and doesn't really solve anything. I didn't really test it  
thoroughly. I just hacked it into my code to get my little test  
program to take key events.

   Just my thoughts. Fix it however you want to but I am thinking a  
_thorough_ test suite is going to be needed to figure out if any fix  
really "works".. or someone could ask on one of the Apple lists ;-)..
