If you have a laptop with a “pointing stick,” or “blue knobby gizmo,” you may have had the experience that your cursor jumps around as you type. This can be especially annoying if you are typing something from an article and not watching the screen.
Here’s how to disable the pointing stick.
NOTE: If you have a Latitude D630, you’ll need to download this driver before following the tutorial. Apparently Dell did not load these laptops with this driver before shipping them out to us. [Thanks to Efrin Ortiz for finding and sharing it.]
