I'm closer to figuring out what is causing it. I haven't entirely put my finger on it so to speak, but as soon as the typing bar moves I stop and look at my hands. I know 100% that it's not the touch pad. It's something that happens with some key or key sequence I hit with my right hand fingers. I don't know about the lights. I don't look at the keyboard when I type so they aren't in my view. I run Adware daily, and do a virus scan weekly. I forgot to check the macro listing, so I'll go and do that now.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
