Surface
The surface on which you use the mouse plays an important role in its tracking. The optical sensor must use the pattern on the surface to track the position of the cursor. Therefore, using the mouse on a glass or otherwise see-through surface will inhibit the ability of the sensor to track the cursor.
Also, if you are using the mouse on a reflective surface, such as a mirror or shiny metal desk, you may also experience tracking problems.
Dark surfaces may cause the cursor to move by itself or jump to different parts of the screen.In all of these situations, try using the mouse on a mousepad or piece of paper. By using the mouse on a white sheet of paper, you can also conserve battery life. Other surfaces that have been known to cause tracking problems are:
Some wood grains
Grooved surfaces
I have personally found that a mousepad from 3M called precise mousing surface in a solid light color works best
