Issue Knowledge Article for Navision Versions up to 4.0

The user opens Navision to find that only the bottom right hand corner of the main menu is visible.  It is positioned as though the main menu is pushed up off the top left hand corner of the monitor.  (all aspects cited here are as though you are facing your monitor).

Is there a solution for this problem OTHER THAN deleting the user's .zup file?
