Some colleagues and I tried to incorporate this into a product in mid-'87.  We
found that the trap for "MenuChoice" was not implemented, even on the Mac II,
although the global "MenuDisable" was being set correctly.  When we complained
to Apple, they told us it was not going to be supported, and not to use it.
Both the trap and the global are documented in the published IM volume V,
dated January '88, though.

I think there were some problems with using the global, but I'm afraid I don't
remember, since Apple was so insistent and we decided not to bother with it.

Incidentally, MenuDisable can return the root item for a hierarchical
menu (the "submenu title").  We were tempted to use this for an odd
syntax, but a preview of this concept at the Boston Computer Society's
MacTechGroup convinced us that this was a Bad Thing To Do.
