	Possible, but problematic.  The NextMenu pointers will be going
every which way, depending on which Window last had the menu.  This is
important because, if the user manages to interact with the Menu in one of
the other Windows before you've chased down all the NextMenu elements, you
could get propelled into a brick wall.  Also, if you have CHECKIT MenuItems,
then one Window may change the state of the CHECKED flags behind the others'
back.

	Again, possible, but problematic.  Largely for the same reasons.
However, because of the strange nature of the SELECTED bit in the current
release, it's much easier to get yourself into trouble.  It may *look*
highlighted, when in fact you just turned it off.

	Stu Ferguson would be able to comment more completely on the
subject, since he wrote Modeller 3D, which has multiple Windows using the
"same" Menus and Gadgets.
