I'm testing my code in using IE9 which lets me also test IE8 and IE7 using the developer tool. It seems that postMessage works when testing in the IE7 mode.

I think postMessage should not work in IE7 but my test says it does and I think it's because I'm using IE9 to do the test.

Is IE7 supposed to support postMessage at all?

No;​​​​​​​​​​​​​​​​​​ only IE8. (and even there not across tabs or windows)

Make sure you're setting Document Mode to IE7, not Browser Mode.

For IE, PostMessages is supported only IE8 and above.
