Use Atlas to implement AJAX-based non-refreshing Chatroom

Atlas is an AJAX Toolkit provided by Microsoft. It encapsulates the Java scripts required for AJAX implementation. It is very simple to use and can directly call the Web Service method, then we Call back the client script through Asynchronous Call. I used Atlas to write a simple AJAX-based non-refreshing chatroom:

To reference the Web Service, add the following client script to the page:

Is the official website of Atlas http://beta.asp.net/default.aspx? Tabindex = 7 & tabid = 47. Although it provides support for non-ie browsers, updating the div in Firefox will refresh the page and won't work on Mac Safari.
