This is the old laptop touchpad issue. Try TOUCHFREEZE (see google)

When typing my cursor jumps to a different point which if I dont catch it fast enough makes a nonsense of what I am trying to say. It doesn't matter how fast or slowly I type. Has anyone else came across this problem and if so how do I fix it. Many thanks
