No, what David was saying was that you need to wait for the button to
be released after it has been pressed. Then you track the mouse, draw
your circles, etc, until it is pressed again, at which stage you
quit. At present your code picks up the mouse button being pressed,
starts drawing circles, and then quits immediately because the button
is still being pressed.
