I do not introduce an unneccessary new object and indeed as I just said I do not justify a privileged frame I carefully explained the function of the object Too bad if you still don t get it If you haven t understood it by now then I don t think I can help I have no idea what you mean with your main point I suggest you have a look at the page I recommended and carefully express your main point in terms of the events that are used If you are not capable or prepared to do that I m afraid I have to cut it short here
