When I open the above URL, it doesn't work in my browser, so I can't click anything to test it, but my guess is that you'r eusing setVisibility on the layer instead of setBaseLayer on th map to 'choose' a base layer. When changing base layers, you should always use setBaseLayer to pick the one you want to be the base. -- Chris > I also have not looked into trying to make the buttons update when > things are toggled in the layerswitcher.
