Air Application - Start in system tray?

I'd be extremely grateful if somebody could help me, or point me in the right direction.

I've been trying to get an adobe air application start in system tray, so far I've used this snippet: http://www.swamicharan.com/blog/air/minimizing-an-air-app-to-systemtray/ which works as described, however no matter what I do I can't seem to make it start, minimized, in the system tray. This is the code I have so far:

Many Thanks.

I think you'll manage by calling dock() at the end of readyToTray(event:Event). To make sure your initialWindow is invisible when it launches you can set it's visible property to false in the application descriptor file.
