Event.MOUSE_LEAVE does not work in AS3

Question

I just threw this super simple code example into the Flash CS4 script framework, but it does not output anything to the console. I just roll the mouse over the window without clicking anything and nothing happens. Why is this not working as I expect?

stage.addEventListener(Event.MOUSE_LEAVE, traceMouse);

function traceMouse(Evt:Event):void
 {
 trace("Mouse Left Stage");
 }

[EDIT] I find Event.MOUSE_LEAVE incredibly worthless. firstly, it does not work in a test environment (at least on Flash CS4 for Mac OS X). secondly, it does not work if MouseEvent.MOUSE_DOWN is currently active:
