I think he touchpad is interfereing with the cursor and text lines and making them disappear as I type so I want to turn the pad off .
I'm hopeless at trying to use the touchpad anyway and only ever use the mouse.
I'm running Windows 7 if that info is needed or makes any difference as to how to disable the pad.
I prefer (need) precise beginner type instructions if you want to help as I don't understand a lot of short pc tech talk.
In other words I don't want you to waste your time as I very much appreciate all help with my pc problems
