(Redirected) Draftsight CAD not working through D1000 Docking Station

I'm experiencing an issue with my Dell D100 dock when using DraftSight.  I have two Dell E2414H monitors attached to my Dell D1000 dock, one plugged into the VGA Port and one into the Display port.  The dock is attached to my Dell Latitude 3570.  When I open DraftSight the drawing environment is displayed in gray color only.  The tool bars surrounding the drawing environment are displayed correctly and are fully active.  When the cursor is moved over the drawing area it disappears from view however the program is still aware of the location of the cursor as the coordinate system tracks its movement in the drawing environment.  This issue persists when a known good drawing is opened.  If I unplug the Latitude 3570 from the dock, DraftSight functions normally on the laptop screen.  I believe that I have the dock driver updated to the most recent version, but Draftsight was working fine and all of a sudden it wasn’t.  Can you help?
