title: How to find WindowRef of Apple Help Viewer application?
body: <p>In my Carbon application upon display of Preference Panes, I have a link which when clicked opens up Apple Help Viewer. </p>
  
  <p>The problem I am facing is the Help Viewer Window is behind my preference pane window.</p>
  
  <p>I would like to keep the Help Viewer window on top of the Preference Pane.</p>
  
  <p>Is there any way to get the WindowRef of the Help Viewer app so that I can use SendBehind API to send the help viewer behind the current window.</p>
  
  <p>Thanks a lot</p>
  
  <p>Regards,
  Marc</p>
