Re: [Laszlo-dev] Help fixing LPP-5926

If you do an "alert(window.setTimeout.apply)", you'll see that it is "undefined" - Hurray for IE! I guess you need to use a function-wrapper, something like here: "http://webreflection.blogspot.com/2007/06/simple-settimeout-setinterval-extra.html";.
This is definitely an IE6/7 issue. The following javascript code fails in IE6/7 if I call apply() when the argument is a function. Calling it with explicit arguments works. 


<body>
   <script>
     function setTimeout_broken() {
       window.setTimeout.apply(null, arguments);
     }
     function setTimeout_works(f, msec) {
       window.setTimeout(f, msec);
     }

     function test () {
       var f = function () {
         alert('hello');
       };
       setTimeout_broken(f, 1000);
     }

     test();

   </script>
</body>
