We've done a lot of work on the metrics for buttons, and I think we are 
pretty much done tweaking them. They are pretty close to the standard 
metrics for the Mac, and I don't want to fiddle with them further.

Marc Culler (the developer of SnapPy) also observed this and did a lot 
of work on patches to Tk to fix the issue. As far as I know the problem 
is licked. Can you run the script below in your version of Wish and see 
if you can reproduce the zombie window issue? (If the issue is present 
the "TopLevel" window will not close when the close button is clicked.)
