To roll back your driver in Windows XP, go to Start --> Settings --> Control Panel --> Mouse. Click on the "hardware" tab. Select the appropriate pointing device, and click "properties." Click the driver tab, then select "roll back driver."
Under the "hardware" tab, there may be more than one mouse. If this is the case, select the one that is not used, follow the settings above, and then select "uninstall." Or, you can go into Control Panel --> System --> Hardware --> Device Manager, and remove the device under "Mice and other pointing devices." Note: if you are on a laptop with a touchpad that you never use, don't remove the touchpad anyway.
Another possibility is that the driver has a corrupted "jump to" setting. This is called different things by different manufacturers, but is a setting where it moves to the default button when a window pops up. It could be moving to the corner instead of moving to the button. Find this setting under mouse properties (as above) and disable it.General rules of mouse problems:
