I am working in chrome v. 12.
I have a jquery call which creates an iframe
$(document).ready(function(){ $(\'\').appendTo(\'body\').
Read here: http://terminalapp.net/submitting-a-form-with-target-set-to-a-script-generated-iframe-on-ie/ Indeed, after I switched to this:
$('').appendTo('body').attr({'id': 'iframeUploader'});
it worked. Tried it in IE8 and FF3.6
