[jQuery] window.document.body reference not working in IE7


Hello,
Any ideas why this doesn't work in IE7? The window opens, but the
page source is <html></html>. Works fine in FireFox.
$("#print-preview").click( function() {
var printPreviewWin = window.open("", "printpreview",
"location=0,status=0,scrollbars=1");
$('[name="print-this-listing"]:checked').parents("div.listing").clone().appendTo(
$(printPreviewWin.document.body) );
});
