Directly after posting the above, the mouse on may machine at home started
giving me problems so I tried the blowing technique. Guess what?  The mouse
horizontal motions stopped entirely.  Even after diddling with the contacts
I got very little motion.  I then took out my handy-dandy voltmeter and
found that one of the two sliding contacts was acting like it was nearly
grounded while the other merrily went between 4 volts and ground as I
rotated the shaft.  After a while, it magically began to work properly.
I suspect that I managed to spit all over the damn thing a probably
shorted the contact to ground with a droplet of spit. 

Moral is: "If you blow your mouse be sure to use spit free air." :-)
