Regarding you're complicated screen that you want to avoid updating,
there's undoubtedly no ez way to predict when somebody is going to
splat over your window. Why not do all your writing to an off
screen bitmap and let your update event routine do the actual
drawing on the screen window. This prevents the problem you
describe with screen savers, et al, blasting your screen, it
will make scrolling faster, too.
