OK, I give up. Unable to reproduce.

parent.opener from external link is always "null" for me (so further
checks are skipped anyway). I tried to open the link with
"window.open('/typo3/')" via javascript, then I have a parent.opener,
but then parent.opener.TS is undefined, which also then skipped the
remaining conditions.

So how do you create a parent.opener that is either NULL nor accessible??

Cheers,
