I use a tween in order to fade in a picture. Unfortunately the picture shifts at the end of the tweening motion.
I tried the macromedia online support and got the following answer:
When tweening just the color effect of a symbol, group or object, select only Motion from the Tweening dialog box. If Tween scaling or Tween rotation are selected, undesirable position shifts may be calculated for static objects in the tweening process.
Unforutunately this does not work.
Thanks in advance.
