P.S. The trackpad works flawlessly.
Cheers.

Edit: After dismantling the whole thing, spraying contact cleaner lavishly, and rubbing the area around the trackpoint, scrubbing the little plastic round thing at the bottom of the "pole", the trackpoint has gone totally dead...

Edit 2: OK, after a while, perhaps after the contact cleaner has been evaporated, the trackpoint starts working again, but it still doesn't quite like to go right......
