User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.2; WOW64;

If a WebBrowser is instantiated in the main of an application and not disposed
(or disposed after some code), it hangs on exit.

Reproducible: Always

Steps to Reproduce:
1.Use the following code :

        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);

            //// HANGS ON EXIT
            //WebBrowser Navigateur = new WebBrowser();
            //Application.Run(new Form1());

            // HANGS ON EXIT
            WebBrowser Navigateur = new WebBrowser();
            Application.Run(new Form1());
            Navigateur.Dispose();

            //// WORKS FINE
            //WebBrowser Navigateur = new WebBrowser();
            //Navigateur.Dispose();
            //Application.Run(new Form1());
        }

2.Run the application
3.Close the application
Actual Results:  
The application hangs on exit, and one is obliged to CTRL-C to get the back
control.

Expected Results:  
The application should exit correctly and one be able to use the shell without
having to CTRL-C.

This makes it extremely difficult to use our mono applications by scripting. A
strange thing is that one does not need to use in a particular way the browser.
Simply instantiating it is enough to get a hang on exit.
