Question: How do I get the result from a QuestionDialog - returning false for both buttons

Trying to use the following question dialog

maplet := Maplet(QuestionDialog("Is x > 0?"));
result := parse(Maplets[Display](maplet));

Displays question with Yes and No buttons but whichever button is clicked the result is always false.  This was based closely on an example from the documentation.

So, how can I tell which button was clicked.  Also, the close button could have been clicked - how should that be dealt with?
