[UI] Gary's UI Enhancements

[Brian Brown]

Hello all!

I have been using the UI enhancements, and found that it isn't  
actually closing system windows - especially debugger windows. If I  
run code like:

  (Debugger allInstances collect: [:d | d dependents detect: [:i | i  
isKindOf: SystemWindow]]) do: [:w | w openInWorld]

I was getting 7 or 8 debugger windows popping up on the screen, they  
just wouldn't close. I had to start over with a fresh image and load  
my code. Now that I'm not using the UI enhancements, I don't have  
this issue, but I sure miss them!
