By jumpy I mean I move my fingers a considerable distance without any response
and then the window suddenly scrolls 1/4 to 1/2 its height.

I recall reading a post by another user about this issue somewhere.  He stated
that the wsp driver does much better than atp.  Like I said, though, it's not a
big issue in my view.  I'd focus our time on more serious bugs that affect
basic functionality before going after this one.
