Access of possibly undefined property useHandCursor

programming flash
1

bold line gives me an error, and I use movieClips which have buttonMode set to true:

var target:DisplayObject;
function overList(e:MouseEvent):void {
    
    target = DisplayObject(e.target);
    
    if (e.target.name == myArray[blueCounter]) {

        **target.useHandCursor = false;**
        target.removeEventListener(MouseEvent.CLICK, clickPlaylist);
    }
    
}
