On the basis of this you may be prevented from clearing the upper field because it's outside the clipping rectangle. From memory one answer was to issue a FrmUpdateForm of your own so that you'd get access to the whole screen. This is a little inefficient because you'll be updating the screen twice - once with the clipping rectangle for the dialog and once for the whole screen but is the simplest solution.
