Need help to with mouse IRQ conflict in WIN XP

I recently got a new "used" computer with Windows XP PRO on it. I have a Logitech 3-button mouse. WIN XP didn't recognise it as having 3 buttons. I downloaded and installed Logitech's Mouseware program. I'm now getting a hardware conflict. Under the Control Panel - System, I get a warning under the mouse. It shows I have a PS2 Logitech Mouse, but it says that there's an IRQ conflict "not enough resourses" [Code 12] between the mouse and something called "I8042prt". I've not been able to find anything on Logitech's website, nor on Microsoft's that addresses this. I can get to the screen to change the mouse's IRQ, but the choice is greyed out, and I can't figure out how to activate it. Any help would be greatly appreciated.

I8042prt is the driver which controls the keyboard and PS/2 mouse for the Intel 8042 controller. The default IRQ for a mouse is IRQ 11, and this usually does not change; nor do I recommend changing it.

You could try disabling the ps/2 mouse port if your other mouse is USB.
I swear, troubleshooting is a science: the best discoveries are always on accident...
