NEWBIE: How to end JOptionPane?

Dear Experts,

I just popped a JOptionPane (thanks, CEHJ!) into a class.  Works beautifully, but after I click "Yes", and the box goes away, and my class would otherwise end, it does not end.  I'm assuming I have to explicitly kill the JOptionPane thread, but I don't know how?  (I'm running it inside of Eclipse.)

This is the code snippet:

Object[] options =
{
"Yes", "No"
};
int n = JOptionPane.showOptionDialog(null, "Some Question? "
                        , "Some Title", JOptionPane.YES_NO_CANCEL_OPTION,
                        JOptionPane.QUESTION_MESSAGE, null, options, options[1]);

return n;


Thanks again,
