The Slide show options now include a "Wait for Sound" feature. With this feature selected, each page will open, play its sound, and remain open until its sound is finished. Or you may choose to loop the page sounds. The sound will start when its page is opened and continue to play until another page with a page sound is opened. In this way, you may attach a sound to the first page that will continue throughout the slide show or you can have new sounds throughout the slide show.
