Jerky animation

Re: Smooth wind streamlines animation transitions
I agree about the jerky animation it used to be smooth but now it seems to go back a step then forward again.
I was watching the development of a cyclone over the west Australian coast when I noticed that the size of the eye jumped at each hour.
When watching the pressure the old version used to display numbers at the isobar intersections how is it better to take this away?
Also thank you for this fantastic program but please make it better by keeping the good parts.
