Why do mouse events trigger twice?

[jingman]

I have some simple script:

Mouse.addListener(_root);

_root.onMouseDown = function(){
trace("bangarang");
}

I debug, and when I press the mouse, it traces TWICE! Why is this? (Does the same thing for onMouseUp).

You don't need to add a mouse listener for this action.

_root.onMouseDown = function() {
trace("bangarang");
};
