words I'm line typing jump to another

[LNocks]

As I am typing, suddenly several words I typed on the current line appear in a previous line - the cursor seems to be jumping.
I am using Windows vista on an HP Pavillion laptop

You are accidentally brushing the touchpad with your thumb or palm, the part of the laptop that allows you to move the mouse by brushing it with your fingers. It's very irritating, which is why I sometimes install a program to turn it off when typing.

Hi, I use touchfreeze, it's a little program, when you type and you brush your hand on the touchpad, the cursor will stay at the right place.
