We just started having this problem with our V.22,when the cursor is moved into the work area the lines of the drawing disappear they will not come back until you remove the cursor from the work area and scroll in or out. Its almost as if the drawing is hiding from the cursor. We have V.22 running fine on another box and it was working fine until a couple of days ago. Ive tried uninstalling and reinstalling the software but it doesnt help, thanks in advance for any assistance that might be offered...Jeff
