Dims off screen, Splines turn into stair steps

[dgschaefer]

WF3, M170

We just implemented WF3 M170 and one of my users is having some issues in sketcher.  His dims end up off screen a lot more than they used to and he's seeing a smooth 3 point spline turn into a staircase of vertical and horizontal lines.  Anyone else seen this?

I've seen the off-screen dims before (who hasn't?), but the staircase spline is new.   His spline looks like a graph of stock market performance this fall.

He's got an FX3500 graphic card running the forceware driver number 162.65.  He's also using a Wacom Cintique 21" touch screen monitor.

Thanks,
