PP 2007, Win xp and 7.
Have a slide with several photos that continue looping (CSS1) following John Wilson's instructions in another one of my post/threads. Problem is when I add a sound track the photos play through once and then stop. The music keeps playing.
I'm trying to get the photos to rotate through and the sound to play until I click(action button) to next CSS2.

tnx for any help,

OK, got it to play and photos to transition BUT the music(song) stops and starts over when photos rotate back to first one.
Is there a way to have the music to continue playing until end of song no matter what photo is showing?

Have a look at

NOTE this method is broken in versions from 2010

Tnx John. 1/2 way there.
Here's what I have.
I have 25 slides in complete presentation.
Slide 1 is a segue (5-6 photos) that fade in and out and loop until the main presentation is started (slides 2-24) by action button to advance to CSS #2 which is slides 2-24 advancing by mouse clicks and then ending with slide 25 with 5-6 photos again fading in and out like 1st slide.
IOW - I had 3 Custom shows with action buttons advancing to next CSS.
I created a new #1 slide according to instruction above, inserted music but couldn't get it to play so I created a new CSS #1 (renaming the other CSS 2,3,4) with action button advancing to CSS 2 and music plays, etc. EXCEPT when I click action button in CSS 2 to proceed to main presentation(CSS 3) the music does not stop...

May have found answer.
When I set up action button going from CCS 2 to CSS 3(main presentation) click Play Sound and select "stop previous sound".. So far so good.

If you have a 'better' way of getting this to work, please let me know.
