Ideally, LockWindowUpdate() should only be used for short periods. It's an easy way to avoid horrible looking refreshes if you have a few controls to update but the locked control should (in my opinion) be unlocked ASAP after the drawing operation(s) that it was locked for have finished. The trail of images are there because the locked control is no longer redrawing itself after something that has been drawn in front of it has been removed. LockWindowUpdate doesn't lock the window so it always looks the same until unlocked. MTCW
