Public bug reported:

The latest reboot brought new software which has wrought terror on my 
Trackpoint.
The behavior is that the trackpoint begins behaving as if one is holding the 
middle trackpad button - instead of trackpoint inputs causing expected mouse 
pointer movement, windows switch, windows scroll.  I've seen erratic pasting as 
well.  Once entered into this mode, the only way to return to normal is to left 
or right click - in the trackpad (left click on the buttons above the trackpad 
don't help).  Then you are safe for the next 15-20 seconds until another 
faux-middle button press happens.  

This behavior is totally new with an update sometime in the last 2-3
weeks (I don't often reboot).
