.wmv link in .swf destroys openWindow


I have a few buttons in a swf, calling popups with stuff and it has worked fine. But since I placed a button linking (get url) to a windows media video in the same movie, the popup buttons refuse to work - if you click the wmv link first.
If you dont touch the wmv link, the buttons work as usual.

Is this a bug or am i doing something wrong? I remember the thing with unique ID on multiple popups, but this wmv link is only a link.
