getURL loader i nyt vindue anden gang

Jeg har postet dette spørgsmål på flere sites, uden resultat, derfor det engelske.

I currently work on a homepage which contains one swf and a named iframe in one html page.
From within the swf a getURL is used to load content into the named iframe, which normally works fine.
But when i open a new window from within the iframe, something goes wrong. The swf getURL starts
loading the content for the named iframe into a new window.
I tried using focus() on the main window, containin both swf and ifame, when closing the new window opened
from the iframe, both no luck.

Anybody got an idea as to how i handle this problem?
I badly need it, since the project is finished, except for this problem.

Short function desc:
Inside the swf there is a range of buttons. When these buttons are used, different content is loaded
into the named iframe. When in admin mode, there is a function for uploading media, which is done
from a popup window. When the media is submitted the window closes and a html string is inserted
into a textarea within the iframe. This works fine, until one of the swf buttons is used.
I cant give any link to view the project, since it is not yet gone public.
