Yes, this was the way I played the embedded sound in Chautauqua 2000. The
problem was I had to pay very close attention to the slideshow, which
stopped me from doing any thing else as an AG operator. So it didn't work
well for such a large event :-(

you could duplicate the slide... so that on the mouse click it advances to
the next slide which is a slidecopy and have the sound triggered
automatically. this will hold the appearance of one mouse click per event.
