Hi, I followed what you told me in last mail and the browser started to get response even to post messages but i am still on able to access the map data. It shows me seg fault. Most of the codes are almost similar to what i found in example for the site. Can you please look over them once and guide me in the right direction. Here is the link to the same https://gist.github.com/georoot/aff2825e0177cb3cc1ae
