As well - you can simply use the standard XP fix - Control Panel your user input devices and play with setting for the mouse/keyboard in there. From that point - if you have any software that came with your device, you will be able to change things there too.
well i was just wondering because i have been messing with my config using cpl standards... I know my razer has software, kinda faulty though which is why i rarely install it, but its a really nice mouse.
