synaptics touchpad generates clicks whilst disabled

[Peter Joanes]

Hello,

I'm running xserver-xorg-input-synaptics version 1.5.99.902-0ubuntu5.1 on a 
Lenovo X300 (i.e. I recently upgraded to Xubuntu 12.04) and use the TrackPoint 
with the touchpad disabled which otherwise would generate unwanted input as my 
hand brushes it.
I have tried several different ways to disable the touchpad, which I think all 
amount to 'synclient TouchpadOff=1'. Unfortunately none of these has quite 
worked, as although the touchpad seems disabled, it still generates clicks 
when the trackpoint button is held down (i.e. whilst dragging).

Thanks,
