ScrollPane

I have a movieClip in a ScrollPane. When the swf that contains this ScrollPane is loaded into my main movie, the main movie freezes for a few seconds. How do I avoid this. Each swf that is loaded into my main movie continues to loop through frames 1 and 2 until the entire movie is loaded. If the movie has been loaded then why still the pause from my main movie, as if it is waiting for the movieClip to load into the ScrollPane.

Hope someone can help.

Thank you very much for any help.
