SetMapView causes the bird's eye icon to show an incorrect value
Hi,
When the map loads, calling SetMapView() causes the status of the bird's eye icon on the dashboard to be incorrect.
I am sure the reason is related to some asynchronous calculations that the Earth Map Control is performing when the map loads.
What I don't like is that the bird's eye icon on the dashboard is enabled, which is wrong when the map loads.
