OpenGL Driver crash with Error 3 SolidWorks must close

Now this is starting to get annoying. It started just after applying the 5.0 patch in SW 2012 and now has continued on in 2013 sp1.0.  If I'm actively working with SW all seems fine. I don't remember the crash while working in SW at least. BUT.. if I let SW sit in the background, using another program or have to go out into the shop to advise on pound on some one. Around 80% of the time when I get back I've got this error up, from either the driver or SW... still looking. All I have it what the hell is going on.

Any ideas ???
