title: Application.application.nativeWindow.activate() problem on Windows
body: <p>I have an AIR application with a system tray icon. When clicked it shows and activates the app. This is working as expected when the app is hidden (docked), however if I select another application so my app is in the background clicking on the system tray icon does nothing. </p>
  
  <p>Oddly I also have a contextual menu on the system tray icon, which has an option to restore, this calls the same event handler as ScreenMouseEvent.CLICK, yet works.</p>
  
  <p>I expect it's something to do with the contextual menu changing the focus, perhaps it's a bug in how AIR works with the system tray, perhaps it's just something I'm missing. Would be good to know if that's the case.</p>
  
  <p>Thanks in advance </p>
