Controlling flash Presentation

I set up a flash presentation. On some slides i have simple timeline animations with a stop command at the end.

The slides advance as necessary when hitting the arrow key, but when i got back to a slide (left arrow) the animation doesn’t play again. It’s just set at the position where the stop command is.

Also, when i get to the last slide and hit the right arrow button nothing happens. I want to be able to get back to the start of the slideshow but don’t know what to do. Isn’t there some built in behavior?

Thanks
