Why is my mouse acting erratically?

1. Your mouse could be dirty. Simply clean the mouse of all dirt and debris. Make sure your work area is also clear of all dirt and debris that could hinder the mouse from properly working. 

2. If your mouse is wireless, the batteries may simply be dying. Change the batteries on the mouse.

3. If those steps fail to work, plug the mouse into another computer to test if it is truly defective at this point. 

4. If your mouse is still acting funny after trying steps 1-3, we suggest you replace the mouse.
