TrackPoint creep is inherent in the design and operation of the TrackPoint(tm). The hardware should detect the slight bias in the system and re-balance the system if the TrackPoint is left alone for a few seconds. It detects a continuous offset in the signal from the pointer and compensates for it. This is probably done in BIOS. This is documented in the manuals for IBM systems using TrackPoint. I don't know if Toshiba has a similar stuff in their manual, but I'm pretty sure that the operation is the same. Bottom line: If you see the pointer "creeping", just leave it alone for about 5 seconds and it should stop. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
