Persistence paid off when I found your post. Worked like a charm, thanks again! I made an applescript so you can toggle on and off the trackpad. Thanks for the relief from the trackpad cursor dance!! Happened once before and wore itself out after 5 days not sure why. Started again yesterday, and after hours of searching other solutions came upon yours, and so far so good!
Thanks for sharing. I bought a new 15 inch MacBook Pro and just started using it. I have the same problem.
I will be typing away and my cursor will jump somewhere else. This is such an annoying problem that no one seems to know how to solve. I originally thought my palms or hands were inadvertently touching the trackpad as I would type. It still does; then I thought I was somehow hitting two keys at once like space bar at same time I would type a comma, etc.
Still no answer. I might just make an appt down at my local Apple store genius bar and see what they have to say. Hopefully yes. It seems Apple has known about the issue. In fact, they had this support article https: Very seldom is it another letter, that starts it. But who on earth can write in that way? Where is Apple in this matter? Andreas Louis. I figured out the solution below for one application, but it might provide a more universal solution—disable the keyboard navigation key-combinations OK.
Yeah, could be. Let us know how it works after moving. Thanks Avery. Kindly let us know what Apple Genius would say if you did make an appointment with them. Thanks Joe! Thank you very much Andreas!

This seems to be something that occurs due to a number of different causes. This really is an annoying problem for Mac OS X users, as it makes typing practically impossible. For many users, this will sort the problem out for you in no time.
