I don't know if you can intercept these messages system-wide. 
I would think you'd need to hook each individual window that uses
a menu.  Is there some global message queue that can be hooked to 
see *all* messages sent to every window/child window running on
the system?  I don't think so.. and if so I would think it would
be terribly dangerous to use.  I could be wrong, maybe there is.
