Scrolling jitter

[J. Landman Gay]

Thanks. On my test devices I see a very slight stutter but it's barely 
noticeable. Apparently on other devices it's worse. I am not using 
container mode since I only have a single field in each case enclosed by a 
scrolling group.

I guess there's nothing I can do about it.
