configuring a 3 button mouse.

[Geoffrey]

I recently upgraded my Mandriva install and now it appears that my 3 
button mouse is emulating a 2 button mouse as cut/paste only works when 
I select buttons 1 and 3, but not with button 2.

The middle button is a wheel and scrolling does work with it, which 
leads to more confusion.

This has always 'just worked' so it's been a while since I tried to 
configure this.  my xorg.conf looks right (to me):

Section "InputDevice"
     Identifier "Mouse1"
     Driver "mouse"
     Option "Protocol" "ExplorerPS/2"
     Option "Device" "/dev/mouse"
     Option "Emulate3Buttons"
     Option "Emulate3Timeout" "50"
     Option "EmulateWheel"
     Option "EmulateWheelButton" "2"
EndSection

Any suggestions would be appreciated.
