startDrag with easing

programming flash
1

Hey! I want to make a page that slides up and down when the user clicks and drags it. I’ve done that using:

var contentBind:Rectangle = new Rectangle(-70, 0, 0, -168);

my_content.addEventListener(MouseEvent.MOUSE_DOWN, contentDragF);

function contentDragF(event:MouseEvent):void{
    my_content.startDrag(false, contentBind);

However I really the need the page to ease rather than just stop suddenly. I’ve had a look and tried a few things without any success, so any help would be much appreciated. Thankyou
