Hi,

I am writing a HyperCard XCMD to use popup menus from resources
(I didn't like the idea of creating the data structures each and
every time I invoked the thing).  I pass the menu id to the XCMD,
and then I do a GetMenu on the id, then go through that menu looking
for submenus, and call GetMenu on them.

This works (so far), and it returns the proper values.  After I use the
menus, I call DeleteMenu on them (also recursively) to take them out
of the list of active menus.

After I am finished with the menus, I make them purgeable again, then
return.

My problem:

In Inside Mac I, it claims that GetMenu should never be called more than
once for a menu.  Yet I have to call GetMenu each time I invoke this
XCMD; however, I do a DeleteMenu for each menu I call GetMenu for.

My question:

Even though this SEEMS to be working, am I creating a time bomb?

                           Thanks,
                             D. Jay Newman
