I see that this your first optical mouse. Try not to move it fast.
Setting its sensitivity up high, so that only a little movement will move
the mouse cursor a long way, is the best way to use optical mice. I myself
use a steel ball mouse, with low sensitivity, for ease of positioning and
less wrist flexing.
Optical mice have a small 17x17 pixel camera in them and do the MPEG
motion-compensation thing to detect motion. If the mouse moves too far
between frames the images won't overlap and it will just end up guessing.
