[jQuery] ajaxsubmit dosn´t send the response to the defined target

[Piet]

Dear all,

I´m using ajaxSubmit to send a form (incl. fileuploads) to my server.
Everthings works well but the response from the server will not
displayed in the defined target (<div id="Preview">). Instead of the
response is display in target="_blank".

What could be wrong???

The submit bind is

   $(document).ready(function() {
    $('#store').bind('submit', function() {
     $(this).ajaxSubmit({
      target: '#Preview'
     });
     return false;
    });
   });

Greetings

Peter
