Hi,I've been trying to set up an overview map but when the map is initially loaded, the overview map is blank. Watching the traffic through fiddler, I can see the images are being passed to the client. If I zoom/pan around the overview map shows up. Any ideas on how to diagnose what is going on?Also, is there a way to control the ratio of the map extent to the overview extent. If my users zoom in too far, they lose the context of where they are at.Thanks.brian <Grid HorizontalAlignment="Right" VerticalAlignment="Top" Width="300" Height="200" Grid.Row="0" Canvas.ZIndex="100">
