We were experiencing intermittent hangs in IE with 2.1.1 GA and commented out the setTimeout in remote.js (jboss-seam-remoting.jar).
Not sure if this goes into your JIRA queue:
asyncReq = new ActiveXObject("Microsoft.XMLHTTP"); var rcb = Seam.Remoting.requestCallback; asyncReq.onreadystatechange = function() { if (rcb) rcb(asyncReq, callback); } /* window.setTimeout(function() { asyncReq.onreadystatechange = function() { if (rcb) rcb(asyncReq, callback); } }, 0); */
