|If you have a ball mouse (a roller ball on the inside of the |
mouse) then you will probably need to clean the rollers on the
inside. You might also want to make sure that you are on a
mouse pad, if you don't already have one.
If you have an optical mouse. Make sure that you are on a flat
and level surface. It helps if it the surface is not metal and if it
is all the same color. You also should check to make sure
that you are using the correct software for the optical mouse
as it could cause some errors in the movements.
