Problem with the mouse on an older XP Pro machine

I have an issue with the mouse on an older XP Pro machine.
The machine boots fine and when the login dialog appears the mouse works
After the login, however, the mouse pointer's area is restricted to about a 10 by 10 pixel area in the lower part of the screen and I cannot get it out of that area.
I've tried scanning for malware, but got a negative result. I've tried system reset without any luck.

Any input?

i would start testing with another mouse; eg if this one is PS/2, then test with a USB mouse , and VV
i suppose you did a scan with mbam?

Thanks for your comment.
Yes, other devices have been tested and mbam is my  tool of choice for these events.

I can kick myself in the bud for this one!
One of our kids had plugged a Wacom penpad into this PC. So the only thing going on was the fight for the IRQ ;-)?

Unplugging the Wacom made the other pointing device behave as one would expect.

Many thanks,
Bye. Michael.
