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. -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
