        The menu manager does a copyBits for the rectangle which the
menu will cover. If there is not enough memory---especially acute
when you are running with 256 colors--it gives up, and just posts
an update event for the rectangle. Thus the application has to redraw
it which is generally slower.
        The solution: get more memory, naturally.
