Mouse cleaning recalibration

I just learned this from a friend who is a computer expert.  You should do this every month ... more often if you spend a lot of time on the computer. 

I was shocked to see this works!    To recalibrate your mouse, click and hold on the S.  Then drag the S toward the e.  If it doesn't work, you might want to clean your mouse.  Stop farting around and go do something constructive
