I have had many IBM Thinkpads (TP) (x40, x41, r40) and it has occured on all models, in addition I have colleagues that experience intermittent issues with their IBM TP’s; where the mouse curser/pointer slams down to the lower right side of the screen and bugs-out with clicks and movement. It has gotten to a point where it occurs 1:3 times I use IE 6 and 7. When it occurs, it completely hinders the laptop!
I opened a case with IBM not too long ago and they basically said, if it doesnt happen in safe-mode then its not our problem.
Is anyone else experiencing this and/or have a solution?
