I have a co-worker who is having intermittent problems with his Layer Properties Manager 'blanking out' (see the attached image). I've never seen this before, and I'm at a loss as to the cause.
His machine is decent, but certainly not a rock-star
Intel Quad-core Q9550 @ 2.83GHz
8Gb Ram
NVIDIA Quadro 600
Windows Vista 64-bit
Running AutoCAD LDC2009, but will also occur when running AutoCAD Vanilla.
Any help would be appreciated!!
