Greg, the mail client you're using does not respect the Reply-To: 
header.  Send things to the list, not to just me.  That way, if I have 
no idea, other people can say something.

You didn't make it clear whether you got a button 2 event when you 
middle-clicked or not.  Copy and paste the text you get when you 
middle-click in the xev window that is generated by "xev | grep -i 
button".  No, nothing's supposed to happen in the GUI, xev is the X 
event tester.  It's there to diagnose problems like this.[0]

Answer these questions:

And provide the output of "xmodmap -pp", which shows the current 
physical button -> button code mapping.  Usually this doesn't change, 
but let's cover all the bases.

[0] And confuse people.  My mouse has left, middle, right, wheel up, 
wheel down, and 2 mystery buttons.  xmodmap reports 10 buttons.  Mystery 
button 1 reports a button 9 event.  Mystery button 2 switches to the 
next window and does not report a button event.  *shrug*
