Weird Graphics Glitch

We are having a weird glitch occur after selecting a face andthen trying to rotate a model. Instead of trying to explain it Iposted video on youtube.

We are having this problem on three computers. Two with Vista32-bit and one with Vista 64-bit. Different video cards, have trieddifferent video card drivers, one of the 32 bit machines is stillSP2.1 and the other machines are SP 3.0. Turning on OpenGL seems tostop the error. Also running it on the other monitor (we have dualmonitors) helps but not always. I can't get the problem to recreatewith SW RX running. Has anybody else run into this problem or canyou think of a fix?
