Hi, I'm not sure what you mean exactly by "making two touches at the same time". The way I initiate a scroll is by placing two fingers (typically my index and middle fingers) on the touchpad and moving them up/down or left/right. It has never begun with any "jump". The change which prompted this thread, was absolutely annoying. e.g., While reading a PDF document. I'd have to remove my fingers and touch the touchpad again, very frequently, in order to continue scrolling. Where as before (and now with the revision rollback) I can completely concentrate on reading the document. Best, --patrick
