I would like to thank all of the persons that responded to my previous posting of this same subject. It turned out that it was a silly question; my routine that handles redrawing those lines was not behaving correctly and as a result the lines were simply not being redrawn. This also accounted for other erratic behaviour in that particular program. Once again, thanks all. Steve
