WebBrowser FAQ:How do I get the site of a new window?

To get the Url that the WebBrowser is navigating to in a new window, use DWebBrowserEvents2::NewWindow3. This method is not exposed by IntelliSense. For information on how to use it, see: http://forums.microsoft.com/msdn/ShowPost.aspx?PostID=7228 for an implementation.
