Progress Bar issues with Screens

Hey, I have been trying to get this, but no luck. Can anyone help?

I have a Screen based portfolio and am loading external swf’s into each slide with the loader and progressbar components.

Beacuse I don’t want all the swf’s to load with the main I have the auto load set to false and am using this code on each slide:

on(reveal) {
myLoader.load(“myMovie.swf”);
}

It all works fine once, but if I leave a slide and then return to it, the swf reloads and the progress bar stays at 100%. Once a swf is loaded, isn’t it cached in the player? I would like it to just play again from the cache, and I can get rid of the progressbar with:

on (complete) {
this.setVisible(false);
}

If its not possible, then how do I reset the progressbar to play again?
Thanks
