Apparently that’s true only of the Application container.

How? This doesn't work: <?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
initialize="initApp();">
<mx:Script>
<![CDATA[

function initApp():Void
{
setStyle("backgroundColor", 0xFF0000);
}

]]>
</mx:Script>
<mx:Panel width="100%" height="100%">
</mx:Panel>
</mx:Application>

But, this does: <?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
initialize="initApp();" backgroundColor="#0000FF">
<mx:Script>
<![CDATA[

function initApp():Void
{
setStyle("backgroundColor", 0xFF0000);
}

]]>
</mx:Script>
<mx:Panel width="100%" height="100%">
</mx:Panel>
</mx:Application>

>if they don’t have a backgroundColor defined, they don’t draw one, so at runtime (at least as I’ve found), you can’t use setStyle(‘backgroundColor’, 0xFF0000);

That’s not true, Jesse. You can set the backgroundColor at runtime even if one isn’t specified in the MXML definition.
