Uh, Duh. Ok, I wondered if it was an IR led but now I
know it is and that
it is working because I can get the mouse to move a teeny bit by running
it over dense text.
I think I have to make a mousepad. Any ideas on the distance between
lines etc? --
Is this a Sun4 mouse or Sun3.
I can send you a Sun4 mousepad.
