/*-- HOW TO DEBUG ---------------------------------------------------------------------------------------
   To debug the script, erase the two slashes before the alert, beneath the browser you're debugging for.
   Example: To see if the script is working for Internet Explorer 5.x
            change: // alert("Internet Explorer 5.x...")
            to:     alert("Internet Explorer 5.x...")
   That way, the next time the script is run, a system alert should show.
   If an alert does not show, erase the slashes before the alerts for other types of browsers, until
   you find the one that does show you a system alert when the script is run.
