It's happened to us all, you've been sat in front of the laptop typing an email to Cousin Jeff in Florida and part way through, without you realising, and the cursor jumps back five lines. You end up with a garbled jumble of out of sequence sentences and don't know what's happened!
 

This phenomenon is called cursor jumping, and it occurs to more people than you think. Just as you were telling Jeff about how well little Jimmy is doing at Tumble Tots, your thumb came very close to the Touchpad, you didn’t touch it, but it was close enough for the Touchpad to magically recognise you thumb was there and to treat it as an input.
 

Some touchpads are more sensitive than others and only a few are adjustable but there is a solution, this free piece of software available from http://touchpad-blocker.com/

 

Runs in the background and quietly disregards accidental clicks based on the duration of the contact with the Touchpad. The software is adjustable to suit your needs but without being overly complicated.
