It is indeed a simple problem -- it simply lacks a good solution.

The 'resume' message does not function normally under MultiFinder.  To
HyperCard, once you open the application, it remains open; it assumes
that other programs won't get in its way.  Since it never sublaunches
itself out of the machine, it never `suspends' itself, and therefore
never `resumes'.  If it did, you could just put the `hide menuBar'
command in an `on resume' handler.

So there are two things you could do to work around this dilemma:
either put `hide menuBar' in an `on idle' handler, or figure out some
way to coexist with the menu bar.

I'd use an idle handler:

	on idle
	  hide menuBar
	end idle

or

	on idle
	  if the visible of the menuBar is true then hide menuBar
	end idle

I don't know which would be faster.

Good luck!
