Hi Balasaheb,
If it is unique to that OS I would be curious to see the net trace from it. My suspicion is that device has a firewall or something similar blocking virtualerath domains. While the V8 control can be called from either the Bing endpoint or VirtualEarth endpoint, some browsers will block cross site scripting so if you are calling from the Bing Endpoint, it calls Virtual Earth from within the V8 control so potentially that is what is getting broken.
Sincerely,
