Almost completely off-topic, but I bought a three-button mouse 
yesterday, partly for easier home Squeaking.  I brought it home and 
plugged into my box running RedHat Linux 8.0 -- and got no three-button 
love at all.    Any troubleshooting advice?  I'm trying to RTM ( 
googling brought up http://koala.ilog.fr/colas/mouse-wheel-scroll/ , and 
I'll try some of that page's tips).

The mouse is a Microsoft Intellipoint 4.1;  it's an optical mouse.
