This.(stage/root) isn't mouseable?

Questions are easy (Have I lost my mind?) – and i don’t think this (scuse the pun) gets much easier. Ahh but the answer…
400x500 stage, single layer (or with the AS in a 2nd layer) with a jpg (80x250) centered on stage
and symbol’d to graphic (or mc).

why doesn’t the following function traces appear when mousing in and out of the stage?:

// or MOUSE_HOVER
this.addEventListener(MouseEvent.ROLL_OVER,MOver);
this.addEventListener(MouseEvent.ROLL_OUT,MOut);

function Mover(event:MouseEvent) {
trace(“In Mouse”);
}
function CloseDoor(event:MouseEvent) {
trace(“out mouse”);
}
trace(“loaded”);

So obviously a newb…thanks, Bryan
