"(For menus read from a resource file with GetMenu, use ...Release-
Resource instead [of DisposeMenu]" (I-352) Which means that if you
want to torch a menu from the menu bar and memory you have to first
DeleteMenu and then ReleaseResource (in your case).

The Menu Mgr is usually pretty flexible but I couldn't get Get/Set-
ItemCmd to work for me using normal command keys. I suspect they only
work for hier-menus but maybe I'm holucinating. I found a work around
anyway (no need to reply).
