[OpenLayers-Users] Overview Map Question

[Robert Buzink]

As I said before, I had the same problem as you, Hans. I solved it by
replacing:

map.addControl(new OpenLayers.Control.OverviewMap());

with:

var ov = new OpenLayers.Layer.WMS( "OpenLayers WMS",
        "http://labs.metacarta.com/wms/vmap0", {layers: 'basic'} );
var options = {
      layers: [ov.clone()],
      minRatio: 8,
      maxRatio: 128
    };
map.addControl(new OpenLayers.Control.OverviewMap(options));

as Christian López Espínola suggested. I still don't understand why the
default doesn't work. Maybe this should be changed? Now it only works for
people who really understand what they are doing, and not for technical-lego
kids like me :-).

Thanks for the help!
