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
