Ok, so basically I have a movieclip of a box fading in and out. I gave it an instance name of 'MC.' The first frame of that animation has a stop (); applied to it.

I then created a button with an instance name of 'startbutton.' Both were placed on the stage, and my AS looks like this:

startbutton.addEventListener(MouseEvent.MOUSE_OVER , startMovie);
startbutton.addEventListener(MouseEvent.MOUSE_OUT, stopMovie);

function startMovie(e:MouseEvent)
{
MC.play();

}

function stopMovie(e:MouseEvent)
{
MC.stop();
}

This works in that when I move my mouse over the button, the movieclip plays, but how do I get the movieclip to loop continuously while my mouse is over the button?
