Why is my mouse acting erratically?
Users who have an optical mechanical mouse (most
common mouse for desktop computers) are likely experiencing erratic behaviour
because the mouse is not clean or is dirty. If you've cleaned the mouse and
continue to encounter issues and this mouse has worked in the past fine
unfortunately your mouse is likely defective. One additional test that can be
done to help determine if this is the case or not is to connect the mouse to
another computer. Otherwise we suggest replacing the mouse
