I don't know if it is actually due to your recent upgrading, but the problem sounds so very similar to the one I had a month ago. I experienced the same things and more, i.e., task bar moved suddenly up to the top, the screen moved rapidly to the right, etc. The problem was I needed a new mouse. I hope that's all your problem is. Maryellen In a message dated 12/11/2009 7:38:01 A.M.
