1) Since IE9 IE has addEventListener - so it has to listen events in standart W3C way -> so it has capture events I use capturing very often - so I forced, instead using on or observe, use addEventListener
2) In the library's code there are planty tones of check - 'if (element.addEventListener)' I believe that they could be replaced by somthing like this: if (element.addEventListener) eventListenerFn = 'addEventListener' else eventListenerFn = 'attachEvent' and than everywhere use - element[eventListenerFn] or somthing else -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
