I can only ever resize the shapes one frame at a time, will I have to remove the keyframes and do them again?
Yeah I'm using a tween - I've made parts of an animation too small, and need to make a those few shapes bigger, but when I resize them at the first frame, they get drawn back to the location and size of the next keyframe
I'm wondering if I can resize them and the proceeding keyframes, keeping them in proportion
Tweens are designed to animate a variety of properties, scale being one of many. If you click on the symbol and resize it, then go several frames and resize it again, you'd expect Flash to animate the resize, right? That's just Flash doing what it's supposed to.
If you go inside the symbol and resize the contents it will do what you want.
