>Description:

running xorg, on an IBM X31 with wsmouse, I intermittently loose the 
middle/right button press functions. pressing l-r combo restores them.

this doesn't seem to happen with xfree86.
        
>How-To-Repeat:
        install xorg on an IBM X31, run wsmouse, use built-in trackpoint
        and buttons.  xev will demonstrate this.
