Hi,  
I’m developing a (sort of-) document viewer in Flash/AS3 and I have to load an external movie where every frame represent a page in the document.

While loading the entire document, I want to show the frames that are already loaded but I can’t find a way: with the Loader class and the ProgressEvent.PROGRESS event I can check only the number of bytes loaded (that isn’t useful for my purpouse) and it seems that I can’t convert the Loader content to a MovieClip before the loading is complete…

Can someone help me?  
Thanks!
