Not fully tested so use with caution ... but toggling offscreen bitmaps off and then on again seems to magically correct this behavior.

sys(602,0) && disables off-screen bitmaps
sys(602,1) && re-enables off-screen bitmaps

Just disabling off-screen bitmaps (without the toggle) seems to also work. But, in searching the UT archives, I've seen many posts expressing concern about VFP's screen update behavior when off-screen bitmaps are disabled.

Comments?
