I recently purchased a Toshiba Satellite M100 notebook, and one function of the touchpad is driving me crazy. Every once and a while, my internet page will revert one page in history when I am using the touchpad to navigate or when my hand just accidentally brushes the touchpad. I'm not sure what I am doing (sliding pressure in certain way, touching specific point, etc) that causes this. Sometimes it is just annoying, but when it backs up while I am typing e-mail and I lose the e-mail it is downright frustrating. I flipped through the touchpad properties panel and windows help and can't find any advice on how to turn this function off, or at least control it. I am running XP using Internet Explorer. Any advice is appreciated. Thanks.
