Bug Description:
WindowAdapter JavaDoc for windowOpened is not in agreement with implementation

The JavaDoc of WindowAdapter for windowOpened says: 'Invoked when a window has been opened.'
However if you run the code, click on open, close the Test Frame, click on open again then you will see that windowOpened is only called the first time the window is opened.
I think the implementation should be fixed to fire windowOpened events every time the window is opened (like what the JavaDoc in WindowAdapter says).
