Exactly - this in fact, was what I was doing, which I've only realised since I understood the underlying mechanism. As soon as I noticed the creep, I'd both become acutely aware of it, and try to compensate for it - which made it persist. When I first saw this, I thought that the trackpoint hadn't correctly returned to a neutral position, so I'd try to provide input and hope that it would, in fact, center itself (and at least I'd keep the mouse near where I wanted it to be). I seem to have never lost this habit - which is, of course, precisely what you /shouldn't/ do, if the hardware is to compensate for some bias. Now, in fact, I'm having fun with it. I can provoke it at will by gently applying pressure in a single direction. After a few seconds, it "notices" that there's an inbuilt bias, and the creep will stop - at which point, releasing the pressure gives a creep in the opposite direction, which similarly lasts for a few seconds before it corrects again. > At least on toshiba my porteget 300CT and 320CT laptops lthis is so, and I > hear from many other toshiba users that this is 'normal'. > > As for minutes of creep (the original poster mentioned it fixing itself > after 45 seconds...) Heh. This would appear to be some kind of time dilation effect due to irritation. It certainly doesn't take that long now... Thanks all! AS
