Has anyone come across this before.

I have a large client server application live in production and all the forms display perfectly fine.

For very good reasons, I have had to move some of the free dbf tables into a seperate location from the main database and include this other directory in the path. There isn't a problem finding any of the tables or the dbc and most of the application works fine

However, the problem is this.

A handful of forms now open in a completely transparent window except for the border. All I can see is the background screen.

The objects are definitely all there and active, and appear one by one as you tab through them. If I minimise the window and open it up again the window displays perfectly fine. I have plenty of free memory and disk space.

Any ideas?
