title: IE10 does not process jquery file upload request
body: <p>I have a strange problem on my Win 8 / ie10 machine. I'm posting my files with the jquery fileupload plugin to an MVC 4 controller method.</p>
  
  <pre><code>$('#fileupload').fileupload({
          dataType: 'json',
          url: baseUrl + "/Profile/UploadImage",
          done: function (e, data) {
              var r = data.result;
              if (r.success) {
                  if (jcrop_api)
                      jcrop_api.destroy();
                  setCrop();
  
                  jcrop_api.setImage(r.fileUri);
                  $('#previewImage').attr('src', '');
                  $("#cropForm").dialog("open");
              }
          }
      });
  </code></pre>
  
  <p>This works great in chrome but when I tried it in IE10 today it started the request but never returned. The MVC Controller method is never hit. There are no errors in the F12 console of IE10. The network tab in the IE console lists the request as pending. Are there any known problems at the moment?</p>
