function ClickObServer(){
   this.deactivateDoubleClicks = function() {
   this.checkClicks = function ( el ){
       for (var i = 0; i < el.length; i++) {
           if( el[i].onclick == null ){
                el[i].onclick = this.myClick;
   this.myClick = function (){
        if( this.clicked == true ){
           return false;
       this.clicked = true;
       return true;
