Ever since I got Lion, I've had two minor issues. 1) When I'm on the internet, I do something to the mouse and the image is zoomed in. How do I un-zoom it? I've been leaving that site, then going back to get it to the normal size. 2) Now my wireless mouse is super sensitive. Again its just me doing something wrong. I'll be on a site and do something to the mouse and it will scroll sideways to the page I looked at before. It's easy enough to scroll back, but it really bites when I'm playing a game because it wipes out what I've been playing. What can I do?
