I have a bouncing ball (very original) that takes one bounce.
If I start out with a fresh drawing and make a graphic symbol, duplicate it
three times, select all the graphic symbols, tween and distribute to
frames -- everything works fine.
If I try and modify the animation, by trying to re-tween (word?), change
the number of frames, or delete frames and start over, I can no longer
tween. Tweening refuses to distribute to frames. I have to create a new file
and new graphic objects and start from scratch.
What is the procedure for revising tweened graphics?
