My Thinkpad 560E exhibits this too.

As far as I know, this is a hardware glitch often seen with the
stick-shaped pointing device found on many notebook computers.  The
stick appears to be generating the "down" signal even when it is
supposed to be in the "neutral" position.  This is a hardware glitch
which surfaces from time to time.

It cannot be corrected by software.
