WHY DOES MY CURSOR DO THE JUMPING ACT?

My MSWord’s cursor suddenly jumps to a previous line while I’m typing. Why does this happen? As far as I know, my hand doesn’t accidentally touch the touchpad of my laptop while i’m typing. Still why does this happen? It’s really very irritating…

It’s easy to brush the touchpad on a laptop without realising.

Try disabling the touchpad and see if the problem persists.

Thanks for the reply pal.
