Sometimes when I'm online and roll the little wheel thing in the middle of the mouse, instead of the page moving up and down, it gets bigger and smaller and kind of goes into the top left hand corner. Not very easy to explain and nobody that I've asked has a clue. I also get amessage about setting tabs when this happens. Not sure how it starts or how I've got rid of it and would love somebody to tell me what to do about it as its a right pain. Ta
