Question about Xml Flash Photogallery Tutorial

I was checking the xml flash photography tutorial and tried to replace the images that appear in the xml for swfs and it worked, but, unlike the images before, which only loaded once, the swfs reload each time you reach them with the back and front buttons.

Is this normal behavior of the swf anytime they are loaded or is it something thats wrong with mine? I have tried loading swfs using the moviecliploader function but i get the same problem when i move to another frame and back.

Anyhow my question is in regard to that specific tutorial. I used the supplied source files. All that is different is that I load swfs instead of jpgs.

Can anyone tell me whats wrong?
