Message_MenusDeleted (&400C9). It is sent when a menu is deleted, without a
selection having been made (mouse click outside the menu, another task pops
up a menu, this task pops up a different menu). Message block+20 contains
the menu pointer for the menu tree which was deleted.
 
Not too sure why you would use it, the draft PRMs don't suggest a use...

If you've ever tried hanging a non-permanent dialogue box off a menu tree
you will be most pleased to hear about such a message - normally the WIMP
closes (but doesn't delete) your window without telling you *anything*
about it. The only way (previously) to detect this was to continuously
poll the window to see when it is shut... Argh!
