Reset your mouse once per year.
You should actually do this every year. Even more often is recommended if you spend a lot of time on the computer.
I was shocked to see how well this works!
To re-calibrate your mouse, click and hold on the Y below. Then drag the Y toward the g. If it doesn't work immediately, you might want to clean your mouse.
I'M SURE YOU WILL WANT TO RECOMMEND THIS TO ALL YOUR FRIENDS
ONCE YOU SEE HOW WELL IT WORKS...
You daft ******. You'll believe anything
