Possible bug with multiple pointing devices

[Joel Feiner]

I was going to file a bug report, but I'm not sure if this is a bug or a 
configuration issue, so I am posting it here first.

I have a ThinkPad, which has a TrackPoint, and I use a USB optical 
mouse.  When I left click to start selecting text with the optical 
mouse, and drag with the TrackPoint, the mouse moves, but no text is 
selected.  It works fine if I use the same pointing device to do the 
button press and the dragging.  I just can't mix the two.  This issue 
occurs regardless of which toolkit the application uses.

I am using evdev for the keyboard and the mouse.  The relevant sections 
of my xorg.conf are here (I am not using HAL for configuration):

Section "ServerLayout"
     Identifier     "X.org Configured"
     Screen      0  "Screen0" 0 0
     InputDevice    "Mouse0" "CorePointer"
     InputDevice    "Mouse1" "SendCoreEvents"
     InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
     Identifier  "Mouse0"

     Option      "Emulate3Buttons" "yes"
     Option      "ZAxisMapping" "4 5 6 7"
EndSection
