My son purchased a new computer running XP Pro and was playing a game when 3 year old son hit a few buttons on keyboard and rotated the vision 180 degrees. He asked me how to return it to normal but I have never experienced the problem. I suggested to do a system restore to a time closest to this happening and it did work, however I have heard of someone else doing the same and rectified it a different way. Can you help with any suggestion? Keep up the good work, I love your show when I get to see it, which sadly is not that often.
