Typically all the menu settings are adjusted in a mouseDown handler in 
the menu group script. It's nearly impossible to track everything as it 
happens. Just set up the menus when the user is actually interacting 
with them.

On OS X, menu manipulations are slow, so be sure to "lock menus", do the 
alterations, and then "unlock menus" in your mousedown script.
