Problem with FireGL X2 + Maya5

I have a problem when I use Poly Sculpt Tool as well as Pint Effects and Paint Skin Weight Tool. When I try to use those tools, the cursor trace will remain on a surface. Alias web only supports this issue with e-support. Does anyone know how to fix it?

Win2k
Maya5
FireGL X2
I'm using the latest driver for video card.

Does you card support onscreen antialiasing? If so turning it off should help.

Thanks for reply, gmask.
In anti-aliasing setting section for my video card, I see two choices. One is "Application preference." Another is "Always on." I don't see a choice to turn it off. I reach this setting window via display setting in control panel. Is there any other ways to turn off anti-aliasing?

I guess set it to application specific

I tried both settings, but couldn't fix the problem.

I hope the problem will go away with maya 6 somehow....

set preferences for both AA and anisotropic filtering to "application controlled"

Also; make sure 'smooth wireframe' is off in the viewport display options.

and of course
the much needed
check later or earlier driver release since this seems to bounce between them.

I'm not sure what anisotropic filtering is. Is there any other way to say it?

Also; make sure 'smooth wireframe' is off in the viewport display options.

It was off, but the problem still stay with me.
I will need to use Poly Sculpt Tool and Paint Weight Tool pretty soon. It's so annoying to use those tools with this problem.
