I have a Flash CS5 movie that contains a background image, an image that I used to create a motion tween with (I believe I did him in isolation mode because the background was grayed out), and a bit of text.
When I go to frame 1, there are two layers, one states it is a tween layer and therefore drawings or shapes cannot be place on it and the other, which I assume is just the background layer will not allow me to create a shape tween. Also, automatically the text and image for the tween are selected and I cannot unselect them. I don't know if that is important or not.
I need to add a simple shape tween to this movie but even if I add a new layer no matter how I create the first shape it will not allow me the option to create a shape tween. I've watched 15 videos on YouTube and everyone does it the same way. Why can't I get the shape tween on my movie??
