I haven't had that problem. Does the demo page work for you?

I'm hoping someone may be able to shed some light...I'm having a problem with what appears to be IE hanging when processing an XMLresponse. Below is a sample of what is going on... $(form).ajaxSubmit({ dataType: "xml", success: processXml }); function processXml(responseXML) { var response = $("myXMLNode",responseXML); // IE hangs, FF ok } I've made sure the headers returned are XML and everything works fine in FireFox. I'm wondering if anyone has come across this?
