I know what you mean 3whiteroses & Lymekiller. I do those same things. Now I am starting to have problems with typing even.
I'll be typing along (not very fast mind you) and I seem to have a muscle spasm in a finger - only it hits squarely on a key. I'm having other similar problems that lead me to believe signals are really getting crossed in my brain.
"Roses", there would be no way on earth that I would even try going to school, much less work. I'm really sorry to hear of your having this kind of trouble.
