I'm still confused as to why you need that call to ExitMainLoop....

And why this gets you Mac behavior -- the usual Mac behavior is for
the App NOT to exit when all its Frames are closed.

note that on any platform, I think this will cause the closing of the
Frame to kill the App, whether or not there are other frames open --
if you app supports having more than one frame open at a time, you
probably don't want that.

This Wiki Page:

http://wiki.wxpython.org/Optimizing%20for%20Mac%20OS%20X

Perhaps the term "Optimizing" is a mistake in that title -- these
aren't really optimizations...

(note the the ID_EXIT is there already, but not the call to MainLoop
(which I still don't quite get the need for..)
