Whoa there! You don't need to do an _InitGraf in a DA! And if you do find a
reason to do it, certainly don't do it relative to A5, because you're likely
to trash your host application's QuickDraw. If you really need to do it (and
you probably don't), make sure you have your own space for QuickDraw globals
and send THAT to _InitGraf.

Now, about this DetachResource business: why? The Menu Manager is perfectly
happy with a resource handle. I've never bothered to detach a menu resource,
and although I can't think of anything specifically wrong with it offhand,
I think I would err on the conservative side.

Finally, re: MS Word and HyperCard, good luck. They've always been notorious
as rule breakers.

Charles, IMHO, don't be patchin' traps from DA's. DA's are ugly enough at this
late stage of the game without trap patches.

But, to address your question, use the activate event that the Desk Manager
sends you to decide when to insert and delete your menu. Much safer, and
has the advantage of being documented practice.
