Hi, Today, my mighty mouse scroll wheel started to seize up (as has happened many a time). To fix this, I turned it upside down and ran the mouse over a piece of paper to get rid of all the gunk. Obviously, I pushed too hard which led to the scroll ball being pushed down. As a result all of my clicks on the mouse are registered as middle clicks and I don't know what to do! I did try opening the mouse, I got to the stage of just about to undo the three screws to access the scroll ball before all my screwdrivers wouldn't fit and I chickened out. What should I do??
