Response is not displayed in the iframe

hi all,

In my application, i pop-up a new window then set the Response display on it. And it worked in all of browser versions in my development and testing environments (IE10, IE9, IE11). But in my customer's browsers, they used the same IE version as mine, it does not worked. They said they updated some security patches from Microsoft. I try to run on Chrome, and it worked. I try some ways to simulate that issue in my PC, but the browser still can show the response. Is there any configurations to solve it on browser? Bellow is my code, Thanks.

var etc = "channelmode=0,dependent=0,directories=0,fullscreen=0,location=0,menubar=0,resizable=1,scrollbars=1,status=1,toolbar=0" + ",scrollbars=no,left = 0 , top = 0 , height=" + screen.availHeight + " , width="+ screen.availWidth ;

var newWindow = window.open('', "MyWindow123", etc );
newWindow.focus();

document.forms[0].target="MyWindow123";

d.method="POST";

d.submit();
