Well, this may not work for several reasons.  Looking for CloseWindow
messages wouldn't always work because programs may exit for other reasons
(via a keystroke command, for instance) and what about programs that are
not actually done after you hit CloseWindow (maybe a requester comes up about
saving your data or something).

Also, my new program, in fact, uses a single menu which multiple windows share.

Well, I use the UserData fields, so please don't muck with them.

I like your basic idea but I think there are probably too many problems
to overcome (such as, what about menus that are built and changed dynamically).
