Supported animations

Hi,

I importd my presenter '09 project into Storyline.

I published but now all the animations that where working fine in Presenter are not in synch anymore in Storyline.

They all moved to the back of the slide, i.e. instead of just happening at the right moment the animations now all happen at the end of the slide.

How come the animations that worked fine in in Presenter are no longer working after they are imported in Storyline?

Thanks!
