Full screen Pop Up

Hi there. Bit of a problem that is bugging me! I know how to make pop up windows using Javavscript. However I want my flash animation to open full screen regardless of the end-user’s screen resolution. Is there any way to detect screen resolution and get your animation to do open like this?

Here is an example - http://www.pixelgasoline.com

Could anyone point me in the right direction?
Any help would be much appreciated! :smiley:
