I've seen a couple of threads about this now, but no satisfactory solution as of yet. My Macbook Pro has started to scroll down to the bottom of pages, application windows etc. Turning it off and on again, or logging off and back on occasionally sorts it out temporarily, but not for long. Has anyone found a solution for this yet? This is on a Macbook Pro 2.66GHz Intel Core i7 with 8GB RAM running OS X 10.9.5, with or without an Apple wireless mouse.
