Do you use a mouse with your laptop and find that the cursor inadvertently jumps around as you are typing?

You may not have realised but this is caused by your hand accidentally brushing the touchpad – so the best thing to do is disable the touchpad when you are using a mouse – some laptops already come with software or a switch to do this, but otherwise this useful program will do it for you.
