I use this simple working function to add events:

function AppendEvent(html_element, event_name, event_function)
{
   if(html_element)
   {
      if(html_element.attachEvent) //IE
         html_element.attachEvent("on" + event_name, event_function);
      else if(html_element.addEventListener) //FF
            html_element.addEventListener(event_name, event_function, false);
   };
}

While doing this simple test:

AppendEvent(window, 'load', function(){alert('load 1');});
AppendEvent(window, 'load', function(){alert('load 2');});

I noticed that FF3.6 addEventListener appends each new events at the end of the events' queue, therefor in the above example you would get two alerts saying 'load 1' 'load 2'.

On the other side IE7 attachEvent inserts each new events at the begining of the events' queue, therefor in the above example you would get to alerts saying 'load 2' 'load 1'.

Is there a way to fix this and make both to work in the same way?

Thanks!
