I have tried your method, but I have a problem, my objective is to have a button which would trigger a fullscreen colour or picture change, but if you rollout from the button it changes back, I would use at least 5 buttons all over the screen with the same function, each would trigger a fullscreen background change.
With the script you provided, thanks again, I have a problem that when the colour change appears it doesn't fade away if I rollout from the button unless I go outside the swf window.
