var _POPUP_FEATURES = 'location=0,statusbar=0,menubar=0,width=190,height =140';

listen('load', window, function() {
listen('click', 'popup-listen', event_popup );
listen('click', 'popup-feat' , event_popup_features('location=0,statusbar=1,menub ar=1,width=190,height=300') );
mlisten('click', getElementsByClass('popup','a'), event_popup );
