Before you start the requery, set the form.LockScreen to true. Then after the requery, set it make to false. This will freexe the screen from updating during the requery.

oform.LockScreen = .T.
oform.oListBox.requery()
oform.LockScreen = .F.

>I have a list box on a form that pulls the info in to a cursor from a very dynamic table. I set up a timer to requery and refresh the listbox every 10 seconds. The problem is that during the requery, it blanks out the listbox for about 2-3 secs while it searches for the info.
