as you can see he made the flash to fit in all the browser, regardless the user resolution so the flash "adapts" to the user resolution. I know some of the mc_symbols have another script in order to move when the user minimize the browser but thats not the point. I just need to know this:
1. How to make my flash to fill the browser like that.
2. If im using a background wallpaper, how big has to be? or I need to use several copies of the same image but with different sizes to acomplish my goal?

Thank you so much for your interest in answering my question.
