I find some like TouchFreeze from http://code.google.com/p/touchfreeze/
On my laptop I just disable the pad and use an external mouse.

HP Pavilion ze2000z about 4 years old. Moving finger over touchpad to move the cursor causes page to jump up and down even when not holding left key down. Is there a way to make the touchpad less sensitive? Is the left key stuck part way down? I just reinstalled Windows from the CD and everything else is working well. Old installation had slowed way down and was unworkable.
