>Hi -
>We have certain forms which have either grid in them or a drop down combo box in them. When you scroll down through either the grid or combo box and select an item, there seems to be a square box that appears on the form where you did the selction from. This dissapears when you refresh the form, however, how do I stop this "ghosting" from happening?
I agree with Mark that video driver problems are often a cause of this. One workaround is to wrap screen refresh function calls in a .LockScreen = .T. / .LockScreen = .F. pair so individual control updates are "batched".
Just don't forget to issue .LockScreen = .F. when you're done.
