This video explores they mystery behind those symbols that Flash automatically creates when you try to tween the untweenable. Watch this video to learn why Flash does this and most importantly what you can do to avoid it!
Important notes
Always convert your shapes, text, artwork to symbols before creating your ending keyframe.
Make sure you select the fill and the stroke.
You can only tween one thing per layer at a time.
If you can’t see the problem, change the background color.
