postMessage doesn't work in recent IE 11 browsers

Question

Hi,
I have some problems in my project.

• parent window : a.a.com
• popup window: b.a.com

When I execute window.opener.postMessage(~~, *) in popup window,
parent window can receive event depending on IE versions. (works in all Chrome versions)

version: 11.1.18362.0 / update version: 11.0.110 - works

version: 11.557.17763.0 / update version: 11.0.130 - works

version: 11.1158.17763.0 / update version: 11.0.185 - works

version: 11.1304.17134.0 / update version: 11.0.175 - doesnt work

version: 11.1425.17134.0 / update version: 11.0.185 - doesnt work

version: 11.1868.16299.0 / update version: 11.0.190 - doesnt work

I cant find any issues about it.
Are there some changes associated with postMessage or CORS policy?

Thanks.

IE development is not supported here on QnA. I'd try asking for help in dedicated forums here.
