I run Windows XP (SP 3) on a Compaq nw8440 laptop with an ATI Radeon X1600 graphics adapter.

When I drag and drop screen  to the Left and click OK, it changes the arrangement to:

I've also tried to do this via ATI's Catalyst Control Center, however the same problem occurs.
How do I force (and Save) the DISPLAY SETTINGS on XP to remember the new screen layout?
