To quote from my T30 documentation: "This is a normal characteristic of the TrackPoint and is not a defect. Cursor drifting might occur for several seconds under the following conditions: * When the computer is turned on * When the computer resumes normal operation * When the TrackPoint is pressed for long time * When the temperature changes" This is slightly different from my 600E documentation which did not list specific cases. But, in either case the fix is to simply do not touch the TrackPoint for a while. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
