Normally, the solution to this would be to tell you to remove any stop(); you have at the end of the timeline. But you may have approached the design differently, so if you can describe how your movie is designed, providing any relevant code, that may help resolve this.
I have just made a endless loop arround my script.. I can't come to any better solutions
I don't know if your response means you've solved it, or if you are trying to describe in very general terms what you designed that isn't working. So if it isn't solved yet, a detailed description of the approach, including your code, will help to determine a possible solution.
