Your app is supposed to handle the commands that are generated from the
selections users make in the menus. I believe the "MenuHandleEvent"
handles things like drawing the menus, inverting the display when an item
is selected, closing the menus when it has been selected, etc.. Unless
you want to do all that yourself, you should use the system stuff.
