Just couple days ago, my TrackPoint started to get weird. It started to move extremely fast on certain direction, and even I set to the lowest sensitivity, it still move extremely fast. Basically I have no control of the track point anymore. I tried to plug in a notebook mouse with trackpoint turned on, I still can't move my mouse. I have to disable the trackpoint. I even tried to replace the red cap but still no use. Does anyone have this problem and know how to fix this? Thanks.
