Figured out what happens if a message box is created for an invisible window, documented it was undefined (Windows and GTK+ behave reasonably but at least Windows is not documented here; Mac OS X shows a sheet attached to invisible where the titlebar should be and then considers the window closed), and added the panic() checks for uncreated Windows.
