It seems that every time I've opened an assembly and touched my SpaceNavigator my screen goes blank and the only remedy is to close the file and reopen without touching the inputs.
System= 8gb Ram, quadcore xeon w/ hyperthreading, 1gb Quadro, SpaceNavigator Ver. 3.14.2, Logitech M570
Software= SW 2012 sp0 64bit edition
Is it me?
