Screen glaucoma caused by the map box!

[Pist-N-Broke]

I've got a nasty little problem. When I'm in the cockpit and open the map box, then close it, where the map box was is totally erased, with a blank grey ghost of where it was.
The truely nasty part is even when exiting the game, then restarting it, the ghosted part of the in game is STILL ghosted out!
As it is now I have three map box sized permanetly ghosted out parts on the screen IN ALL VIEWS. One is bang dead centre of the view.

WTF is going on? Any ideas?
