Upload varioius file problem

When i try to upload a "first" file all works great, but when i try to upload another fila without a reload it's works too but i can't get a message from the succesful, what happen guys?

I have the same problem :/

I found it. just write the http.onreadystatechange = handleResponse; statement on the end.

http.open("GET", 'imageupload.php?uploadDir='+uploadDir+'&uploader='+uploader);
http.send(null);
http.onreadystatechange = handleResponse;

then it works also with IE

Thanks man, now works great

Peter thankeyou sooo much!! i spend 2 hours in this problem
