[SPARCbook] Lost horizontal on mouse, ideas?

[Peter L. Wargo]

Well, my 3GS has been sitting for some time ( a month or so) while I
recovered.  A visit friend wanted to check it out, so I fired it up, only
to find that the horizontal has failed on the "eraserhead" mouse in the
keyboard.  Vertical works fine, as do the buttons.

Anybody know if this is a common thing, that can be fixed w/cleaning, or
if I need to replace the mouse?
If so, can I get replacement units easily?

TIA,

-Pete
