Проверьте пожалуйста код:
Переписал этот (сам код не менял, только стиль написания)
http://javascript.ru/files/event/event.js
Но он почемуто перестал работать в IE
Кто сможет обьяснить почему???

var $e={
		guid:0,
		fixEvent:function (event) {
			event = event || window.event;
			
			if(event.isFixed) {
				return event;
			}
			event.isFixed = true;
			
			event.preventDefault = event.preventDefault || function(){this.returnValue = false};
			event.stopPropagation = event.stopPropagaton || function(){this.cancelBubble = true};
			
			if(!event.target) {
				event.target = event.srcElement;
			}
			
			if(!event.relatedTarget && event.fromElement) {
				event.relatedTarget = event.fromElement == event.target ? event.toElement : event.fromElement;
			}
			
			if(event.pageX == null && event.clientX != null) {
				var html = document.documentElement, body = document.body;
				event.pageX = event.clientX + (html && html.scrollLeft || body && body.scrollLeft || 0) - (html.clientLeft || 0);
				event.pageY = event.clientY + (html && html.scrollTop || body && body.scrollTop || 0) - (html.clientTop || 0);
			}
			
			if(!event.which && event.button) {
				event.which = (event.button & 1 ? 1 : ( event.button & 2 ? 3 : ( event.button & 4 ? 2 : 0 ) ));
			}
			
			return event;
		},
		commonHandle:function (event) {
			event = _$$.$e.fixEvent(event);
			
			var handlers = this.events[event.type];
			
			for(var g in handlers) {
				var handler = handlers[g];
				
				var ret = handler.call(this, event);
				if(ret === false) {
					event.preventDefault();
					event.stopPropagation();
				}
			}
		},
		add:function(elem, type, handler) {

				elem = window;
			}
