Try the Vista forum but it sounds like a setting or user issue. One owner didn't know how the pad worked with how/what it did when we slid the finger along the right edge. For them they didn't want a lesson on trackpad use so we disabled it and put in a mouse.
I have an HP Pavilion laptop entertainment PC with Vista. Periodically, when using the touchpad pointer, the active window will zoom up to 150-200%. I've tried slowing down the speed of the touchpad response to no avail. Does anyone else have this problem or know how to fix it? Thanks
