I've been using classic tweens for my animations. Motion tweens don't quite work the way I needed, so I stuck with classic. Strangely, when I went to work on the animation today the option to use classic tweens was gone. When I right-click for the tween menu, I can't even see the option (it's not that it's greyed out, it's that it is GONE).
What's going on?
I went back and looked at previous animations I created using classic tweens and I can no longer create new ones.
I use Flash CS5 and Windows 7. I will un-update or do whatever I can to get classic tweens back until this project is complete. I can work out a way for motion tweens to suffice after this, but not when I'm under a deadline.
