Thanks for the info Mike, but those satellite labels were just an example.
So it seems clear that you can't adjust the visibility of a layer that is a part of a MapType. Design flaw, no flaw, whatever .. I can accept this. What I still don't get is how a MapType is notified to be redrawn. If you look at Overlay they specifically have initialize() and redraw() methods. There are no such methods for a MapType. I know this is an internals question but I'd still like to understanding what is gong on. Clearly the Map notifies the MapType to redraw itself, but it doesn't appear to be part of the public API.
