[F8] how do I skip the preloader if movie is already loaded from before?

Hi

www.aqueledesign.com/tekilla

Here.. once you click on one of the characters it loads the content.. and when you go back to home and click again it goes for a LITTLE INSTANT to the preloader (you can see the preloader image) is there a way to stop this? Like add some code before the preloader to check if the movie is already loaded and if so skip it?

thanks!
