How to show MouseOver effect on dropable region while dragging a MovieClip?

Question

Hello friends,
I am creating Drag and drop flash application.
While dragging an instance of a movieclip I want also the dropable region to show effect like MouseOver case.

Thanks for taking interest.
I did the first part of your reply already, but  How to check if a MovieClip is being dragged?
Say, I have two MovieClips
TargetToDrop_mc
DropableRegion_mc
TargetToDrop_mc.addEventListener(MouseEvent.MOUSE_DOWN, gotMouseDown);
TargetToDrop_mc.addEventListener(MouseEvent.MOUSE_UP, gotMouseUp);
TargetToDrop_mc.addEventListener(MouseEvent.MOUSE_OVER, gotMouseOver);
TargetToDrop_mc.addEventListener(MouseEvent.MOUSE_OUT, gotMouseOut);
DropableRegion_mc.addEventListener(MouseEvent.MOUSE_DOWN, gotMouseDown);
DropableRegion_mc.addEventListener(MouseEvent.MOUSE_UP, gotMouseUp);
DropableRegion_mc.addEventListener(MouseEvent.MOUSE_OVER, gotMouseOver);
DropableRegion_mc.addEventListener(MouseEvent.MOUSE_OUT, gotMouseOut);
function gotMouseDown(EventReceived:MouseEvent):void {
    EventReceived.currentTarget.startDrag ();
function gotMouseUp(EventReceived:MouseEvent):void{
    EventReceived.currentTarget.stopDrag();
function gotMouseOver(EventReceived:MouseEvent):void{
    EventReceived.currentTarget.alpha=0.5;
function gotMouseOut(EventReceived:MouseEvent):void{
    EventReceived.currentTarget.alpha=0.7;
Now plze guide me on basis of above.
Thanks,
