	I have an Optical Mouse made by Mouse Systems that is
"blind" in one eye. The horizontal eye, to be exact -- which is the one 
with the visible red LED. The red LED glows nicely but the sensor must be
broken because I cannot budge the cursor in the horizontal direction.

	Vertical movements work perfectly but I cannot budge the cursor in
the Horizontal direction. I suspect that the problem is with an optical
detector labelled D1 and which looks like an 8-pin IC with glass enclosure
in which one can see a linear array of 4 cells which obviously detect the 
sweep of the red LED light reflected from mouse pad grid lines linearly 
across the array of 4 cells during horizontal movement.

	My question is:

	What is the glass enclosed IC detector element called? Where might I
buy one?

	Might you have a dead optical rodent from which I might do a "corneal
transplant"? :-)

	Thanks
