Bzzzzt. I'm sorry. You were all very close, but step down behind
the curtains and we'll have some fabulous consolation prizes for
you.

The right answer is, of course, to check the windowKind of the
FrontWindow just before you call MenuSelect or MenuKey - it's
that simple. There won't be any noticeable delay before the menu
appears either (not even on the Classic...)

This is the way it's done in the Think Class Library, among
other places.
