does anyone know how to select a song to play through an entire slide show presentation? i can only figure out how to play a song during one slide, and then it stops once i switch slides.

edit: nevermindddd. robb or linda or someone can delete this. in case any one needs/wants to know though, if you go to slide transitions, you can select a 'sound' to play, so you take a regular mp3 and convert it to a .wav and then you can add it.
