hey everybody,

have a minor AS/JavaScript problem here…

what i have is a button loading an image in a new window using this code:

```auto
b1.onRelease = function(){
	getURL("javascript:window.open('images/wallpapers/rocks.jpg');void(0);");
}

```

what do i need to add to set the new window’s backround color to black???
