Some questions on using sound in PowerPoint..
(1) - if I want a piece of music to play in the background - do I have to put that on the first slide - I've tried it on the third slide and it won't play on slides one and two?
(2) What's the difference between "Play across slides" and "play in background"
(3) What's the difference between "loop until stopped" and "Rewind afer playing" and when would I use either/both
(4) why would I use a bookmark?
