Flash 8 Pro presentation mode.. mc's don't play on new slide?

I am trying my hand at using Flash 8 Pro’s “presentation” feature… It’s pretty slick in that it lets you “layer” slides based on slide-spanning topics, but it also deviates a bit from regular Flash behavior, and I am having a hard time achieving a specific behavior:

In each slide (not nested), I wish to introduce a new movie clip. This movie clip runs for a few internal frames and stop()‘s at the last frame. What I don’t get, however, is why does only the first slide’s instance animate? Subsequent slides’ copies of the mc freeze on the last (stopped) frame and don’t animate.

(see fla in attached zip)

What’s more, why don’t the movie clips replay when I visit a played slide?
And why does my actionscript in frame1 of Slide2 get evaluated in frame1 of Slide1?? I would expect my trace() in Slide2 to get called only on play of Slide2…
