title: Make browser window blink in task Bar
body: <p>How do I make a user's browser blink/flash/highlight in the task bar using JavaScript? For example, if I make an AJAX request every 10 seconds to see if the user has any new messages on the server, I want the user to know it right away, even if he is using another application at the time.</p>
  
  <p><em>Edit: These users do want to be distracted when a new message arrives.</em></p>
