IE9 Permission Denied when writing to a window - ExtJS 4 App

Question

var display_setting = "toolbar=yes, location=no, directories=yes, menubar=yes,";
    display_setting += "scrollbars=yes, width=750, height=600, left=100, top=25";
    var printwin = window.open('', 'printwin', display_setting )
    printwin.document.open()
    printwin.document.write("Testing")
    printwin.document.close()

Why does the above code generate a "Permission Denied" error in IE9, but works perfectly fine on Firefox or Chrome? Is there a work around? It is an ExtJS 4.1 application is running on an intranet from a single domain. It uses the ExtJS history feature which may be a factor.

Thanks

I have tested with the above code, in IE I have found only one issue, that is in the last line you haven't declared the object win... if you give the details of your requirement then I will help. I have modified your code and tried its works fine for me in IE.

Here is the test code. If you want to close the window use printwin.close() instead of printwin.document.close().

<script type="text/javascript">
function openwindowIE(){
var display_setting = "toolbar=yes, location=no, directories=yes, menubar=yes,";
    display_setting += "scrollbars=yes, width=750, height=600, left=100, top=25";
    var printwin = window.open('', 'printwin', display_setting )
    printwin.document.open()
    printwin.document.write("Testing")
    printwin.document.close()
}
</script>
<input type="button" onclick="openwindowIE()" value="go"  />

If I'm not mistaken, IE thinks, that about:blank (which you are trying to open, I guess) is an insecure website and thus you aren't allowed to communicate with it.

If I'm not mistaken, you could open any other (empty) html document and write in it, instead.
