Every once in a while my mouse pad gets a mind of its own and changes settings. One day it just decided to start clicking when I tapped the pad. I eventually figured out how to make it stop if need be, but left it for the time being. But now that I've gotten used to tapping my mouse pad to select an item, it decided to stop doing it.
Now when I tap my mouse pad it no longer clicks. Also, my scroll bar at the side just moves the mouse instead of scrolling through the page.
I tried going into my control panel, but now the options that were once there to change my mouse settings are no longer available.
Is there an easy way to fix this? I'm working on Windows XP, and I don't really know a LOT about computers. So if anyone could help me in the simplest way possible it would be MUCH appreciated. I like my clicky mouse pad, haha.
