Preloader
I have one idea that could do everything you wanted. If you save each movieclip as its on move with its on preloader, then when they click on one of the buttons in the main form it loads the external movie. This will also mean they can continue lookin around the main movie while they are waiting for the other one to load. I could make an example of what i mean if you would like, just email me
nosmo-kings@hotmail.com. I hope this will help.
