Boa tarde, tenho um TitleWindow (janela1) que chama outro TitleWindow
(janela2).
Quando fecho a janela2, ocorre o erro abaixo, parece alguma coisa
sobre foco, mas não dá certo de jeito nenhum.
Fecho a janela assim: PopUpManager.removePopUp(this);
TypeError: Error #1009: Não é possível acessar uma propriedade ou um
método de uma referência de objeto nula.
