Problem with loading Bing map in Bird's eye view using UMap AFComponent in Flex

I am using Umap AFComponent 1.8.1 in Flex 3.5 for showing Bing maps. When I try to load a map in Bird's eye view, map flickers. Fiddler log shows a lot of requests done by the map proxy for different latitude and longitudes. Finally proxy does the request for given location. How to make the proxy just do t开发者_C百科he request for given location and not unwanted requests.

This is how map is initialized

var map : UMap = new UMap();
map.addControl(new BingControl());

Add Bird's eye manager

var birdseye = new BirdsEyeManager();
map.addManager(birdseye);

Change to Birds eye

map.setMapType(birdseye.mapType);

Initialize the proxy

MapProxy.initialize("../Mapping/Proxy.ashx");
proxy = MapProxy.getInstance();
proxy.getToken();

Getting the map location ,loading the map is done by UMap component.

Please help.

Thanks

Note: If I load the map in Road view or Aerial view and then change to Bird's eye it works as expected.
