Under Windows 95, and attempt to add
additional menu items to a MenuBar once
the MenuBar's peer has been created leads to
weird behavior; the menubar adds
each item south of the menubar, increasing
the menubar's height for each added
menu item. These misplaced menu items are
invisible (though they respond to
mouse clicks). This bug forces us to either
a) destroy the menubar and rebuild
it everytime it is to change (resulting in
mucho flicker - sound familiar), or
b) attempt to write our own version of the
menubar (we're already trying this -
but the result is buggy).
