I am creating the Title Window Component once, and then
showing it with PopUpManager.addPopUp, and hiding it with
PopUpManager.removePopUp. I need to run some logic each time the
PopUp is shown. However, I can't figure out what Event is triggered
when the TitleWindow is "opened". The window is there, it's just
not being displayed. This make me think that "show" would be
triggered, but it is not. I also tried "add", but this threw a RTE.
