What kind of mouse is it ?

I know redhat and XP come with a lot of supported drivers for quite a bit of hardware maybe the drivers are corrup uninstalled or other try reinstalling the drivers from the disk you get with the mouse or if you dont have it try a google search for your make of mouse +drivers downlaod and install them other than that i dont think the mouse is damaged because you say it works in redhat and driver issues are a good possibility
