when a modal dialog has been shown and hidden from
    within an other modal dialog, the latter dialog can't be
    hidden anymore. Calling Dialog.hide() or Dialog.setVisible(false)
    has no effect. Although the dialog remains visible,
    Dialog.isVisible() return false. I've included an example
    source, listed below.

   Run it, press "test". Then press "new" in the dialog. In the new
   dialog, press "dismiss". Then press dismiss again. The dialog
   refuses to go away. It's still visible, although isVisible ()
   returns false. There is _no_ way to get rid of the dialog. */
