I've imported a .swf video to a slide in Presenter 8. The slide is also locked to force users to view the entire video. The video plays fine the first time it is accessed, but if a user returns to the video slide after the first time it is viewed, the slide is unlocked and users can jump to the next slide before the video is done. The problem is the audio from the video continues to play causing it and the next slide's audio to overlap one another. How can I stop this from happening?
