The Position is off screen error message is typically caused by a Screen which is larger than the workstation monitor can display.
Like Dave suggested above, you can either change the Display properties Font or Resolution so that the entire screen will be displayable or you can re-design the screen so that it will fit onto a worst-case (a.k.a. lowest resolution) display - typically 640 x 480.
Good Luck,
