Regarding to AppDomain.CurrentDomain.UnhandledException and logging.

Hi,

I used to work with Logging but can't regonize it how to do it with the right way.

AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;

private static void HandleException(Exception ex)
        {
            if (ex == null) return;
            this.logger.WriteMessage("");
// Do I need to put the Thread.Sleep here?
            MessageBox.Show(OnScreen_v2.Properties.Resources.UnhandledException);
            Environment.Exit(1);
        }
Do I need to put the Thread's sleep method there? I need to write error message to local disk.
