1. Startup netTunes with a second display attached
2. Move iTunes window completely onto the external display
3. Close netTunes
4. Disconnect your MacBook from the second display and go home (miles away from the external display)
5. Startup netTunes

The iTunes window is being 'shown' on the second display - which isn't there!

How do you get to see the window without plugging in another monitor?
