It might be a script which polls the server to check if there are any new PMs, search for AJAX to learn more. It's however not good to do this with JavaScript since you must have pretty low polling intervals to get new messages quickly.

There are ways to force an open connection to the server, and thus allow the server to send data whenever something happens. But there are potential problems with this approach since the browser might timeout the connection or appear to never stop loading the page since the connection isn't closed when expected.
Try searching the web for forcing an open connection to a web server, or something like that.

I'll move this to the flash section since I assume the chat is made in flash. And maybe you can extend the chat to get IMs.
