I'm not sure that the Load event is the right place for resizing and moving a form. When this event occurs the form is not "completed" yet, and an intrinsic Resize event occurs after the Load event. The sequence of events when you open a form is:
Open → Load → Resize → Activate → Current.
Moreover, why do you bother using the DoCmd.MoveSize method while you could use:
Me.Move Width:=1440 * 8, Height:=1440 * 6
Which is at least standard in its arguments (oddly, MoveSize uses arguments for Right and Bottom coordinates, while all standard coordinates in Windows are Left-Top based).
