I’ve had this problem with my flash work in the past where a graphic will glitch when moving. An example of what I mean is shown halfway down this website: [http://www.republicofcode.com/tutorials/flash/tweenclasseasing/](http://www.republicofcode.com/tutorials/flash/tweenclasseasing/)

The two rolling balls have an occasional flicker on part of the graphic. What causes this?
