Tooltip, он же Hint, он же всплывающая подсказка, на AS 2.0. Рабочий вариант класса, который использован мной в готовом приложении. Выкладываю as is, кому нужно, тот разберется.

class Tooltip
{
	private var clientList:Array;
	private var currentHintIndex;
	private var globalMovieClip; // movieClip to get mouse coordinates from, usually _root?

	private var delayCounter:Number;

	private var hitTestCalled:Boolean;
	
	public static var interval:Number = 50; // ticks interval in millisec
	public static var delay:Number = 700; // delay mouse stops and before hint shown
	public static var movieClipName; // movieclip himself
	
	private var hint;
