This has everyone puzzled here.
We have a product that we designed around an 800x600 resolution. On all the machines at our office and at my house (Win95, Win98, WinNT Workstation, WinXP Professional) it looks fine. But on one particular client's workstations, the screen is not showing at 800x600. They get a screen approximately 200x150 or 400x300. It's not the whole screen. They can re-size the screen to make it look ok, but the next time a screen appears it is back to the small size.
Has anyone here ever encountered this? Is there something we can do to fix this? They are running Windows NT workstation on their client PCs and Windows NT server on the server that the program is being accessed from.
