Menu gets hung up

Question

In the attached file, for some reason, when the menus drop down, they frequently get hung up.  (stay down, slow to move back up into the hidden position, etc.)
I really need to correct this as this will be the main website for our school district and I need it to look professional. 
Any help is greatly appreciated. 
Thanks.

Ooops, i was looking at the end of the timeline, didn't know i could scroll left to see frame 1. I'm not sure exactly to as why the Mouse out event listener is slow on capturing a mouse out event. If you do a slow mouse out it works while doing it fast it cannot capture sometimes. I revised your code to use the ENTER_FRAME instead and do a check if the mouse goes beyond the Rect area a mouse out and it yields perfect results.
Replace frame 1 with this code instead:
import fl.transitions.Tween;
import fl.transitions.easing.Regular;
import fl.transitions.easing.Elastic;
Menu_Cont.District_Rect.alpha = 0;
Menu_Cont.District_Btn.addEventListener(MouseEvent.ROLL_OVER, DistrictRollOver);
Menu_Cont.School_Board_Rect.alpha = 0;
Menu_Cont.School_Board_Btn.addEventListener(MouseEvent.ROLL_OVER, SchoolBoardRollOver);
Menu_Cont.Parents_Rect.alpha = 0;
Menu_Cont.Parents_Btn.addEventListener(MouseEvent.ROLL_OVER, ParentsRollOver);
function DistrictRollOver(event:MouseEvent):void
var DistrictMenuTween:Tween = new Tween(Menu_Cont.District_Menu, "y", Regular.easeOut, Menu_Cont.District_Menu.y, 45, .5, true);
Menu_Cont.District_Rect.addEventListener(Event.ENTER_FRAME, checkDistrictRectIfRollOut);
function SchoolBoardRollOver(event:MouseEvent):void
var SchoolBoardMenuTween:Tween = new Tween(Menu_Cont.School_Board_Menu, "y", Regular.easeOut, Menu_Cont.School_Board_Menu.y, 45, .5, true);
Menu_Cont.School_Board_Rect.addEventListener(Event.ENTER_FRAME, checkSchoolboardRectIfRollOut);
function ParentsRollOver(event:MouseEvent):void
var ParentsMenuTween:Tween = new Tween(Menu_Cont.Parents_Menu, "y", Regular.easeOut, Menu_Cont.Parents_Menu.y, 45, .5, true);
Menu_Cont.Parents_Rect.addEventListener(Event.ENTER_FRAME, checkParentsIfRollOut);
function checkDistrictRectIfRollOut(oEvent:Event):void
   var mcRect:MovieClip = Menu_Cont.District_Rect;
   if(mcRect.mouseX > mcRect.width ||
   mcRect.mouseX < 0 ||
   mcRect.mouseY < 0 ||
   mcRect.mouseY > mcRect.height)
       mcRect.removeEventListener(Event.ENTER_FRAME, checkDistrictRectIfRollOut);
   MenuMouseOut(mcRect);
function checkSchoolboardRectIfRollOut(oEvent:Event):void
   var mcRect:MovieClip = Menu_Cont.School_Board_Rect;
   if(mcRect.mouseX > mcRect.width ||
   mcRect.mouseX < 0 ||
   mcRect.mouseY < 0 ||
   mcRect.mouseY > mcRect.height)
       mcRect.removeEventListener(Event.ENTER_FRAME, checkSchoolboardRectIfRollOut);
   MenuMouseOut(mcRect);
function checkParentsIfRollOut(oEvent:Event):void
   var mcRect:MovieClip = Menu_Cont.Parents_Rect;
   if(mcRect.mouseX > mcRect.width ||
   mcRect.mouseX < 0 ||
   mcRect.mouseY < 0 ||
   mcRect.mouseY > mcRect.height)
       mcRect.removeEventListener(Event.ENTER_FRAME, checkParentsIfRollOut);
   MenuMouseOut(mcRect);
function MenuMouseOut(mcRect:MovieClip):void
    var mcMenu:MovieClip;
    if(mcRect == Menu_Cont.District_Rect) mcMenu = Menu_Cont.District_Menu;
    else if(mcRect == Menu_Cont.School_Board_Rect) mcMenu = Menu_Cont.School_Board_Menu;
    else mcMenu = Menu_Cont.Parents_Menu;
    var cTween:Tween = new Tween(mcMenu, "y", Regular.easeOut, mcMenu.y, -62, .5, true);
