When typing on the keyboard the curser will jump to previous positions and makes typing very hard work because you end up typing rubbish unless you pay very close attention while you work. Does this in all software applications and even with not touching the touchpad.
anything I can do that doesn't involve a download?
Temporarily disable the touchpad & see if the cursor still jumps around.
i am not touching the touch pad. so i dont believe this to be the problem!
