I've got Voodoo Rush single planar card and after installing drivers my mouse pointer get blurred...What is going on?Anybody can help me?

Ehm, what exactly do you mean with "blurred" ?

The Voodoo Rush does have Hardware cursor support, so any Mouse cursor (including custom ones, e.g. in Games) should be fine.

If it's broken (in terms of error pixels or lines, or even a complete Box of dynamic error pattern), this could indicate that the Video Memory Region normally reserved for the Mouse Image is being used for other purposes.
(I've seen this particular effect a couple of times, commonly it was either Bios related or the Driver was incorrect/needed to   be reinstalled, or possibly indicated an IRQ/Resource conflict)

Nasty problem to troubleshoot, though , hard to nail down exactly :-/

Maybe he's using too much Glide! :P

Glide Gluttony! :D
That will smudge everything!  ;)

Yes,cursor resemble a stick...it is build of several dots...Where should I look to repair it?

Does the problem only appear when you move the mouse pointer?

I'm wondering if trails are turned on?

Otherwise I'd presume a problem with the memory used for the hardware cursor as FalconFly said.

You know what? I just turned the trails on and cursor is OK :o??And again without the trails -it is corrupted...I dunno ???Could it be a driver malfunction?I have an Alliance Promotion At3D 6MB PCI on Voodoo Rush-which driver version would be the best?

For as long as it is the latest Driver (V3.01.00) , you should be fine.
