Loosing mouse pointer on centos 4.1

[geisj at pagestation.com (Jerry Geis)]

I have a dell inspiron 8200 laptop . Install went fine.
After booting and using my laptop for a while my mouse pointer
just disappears.

Any ideas?
Any way to restart my mouse pointer?

I tried doing CTL-ALT+F1
and ALT_F7 thinking that would reinitialize the mouse but no.

Only thing that works is reboot.

THanks,

Jerry
