Hi,
It may be that it is being restored to a position off-screen, due to having previously been used in a larger screen size
You can attempt to find it using one of these ideas:
1) Immediately after restoring it, press Ctrl-F7. Then use the arrows keys to move leftwards and possibly up. If you're lucky, it will come into view.
1 1/2) Same again, but press an arrow key only once. Then wave the mouse around and see if it comes into view
2) Delete the foxuser.dbf file and restart FoxPro. everything reverts to default position.
