TightVNC seems to crash display drivers

Howdy ya'll

I'm having a problem. I have many rigs running stable without touching them. However, when I start playing around and remote desktop-ing into them, the display driver for the primary card (GPU 0 when I use --gpu-reorder in cgminer) crashes, and the card goes SICK.

It's not a 100% reliable correlation, but when I leave them alone, the drivers run stable.

I'm using Windows 7 32 bit, AMD 13.4 drivers, and TightVNC 2.7.

Anyone else experience this?
