Keeping the custom cursor over content

[lzooml]

To use a custom cursor, simply used the following piece of code;

Mouse.hide();

stage.addEventListener(MouseEvent.MOUSE_MOVE,follow);

function follow(E:MouseEvent)
{
	cursor_mc.x = mouseX;
	cursor_mc.y = mouseY;
}

cursor_mc.buttonMode = true;

However, when I move the cursor over a content, say, a movie-clip, it stays under the movie-clip.

How can I always keep it over content ?

Thank you.
