Topic: Tiltviewer or the Flashprogramm is destroying my Dropdown Menu

I've downloaded Tiltviewer so that i can put up some Photos on my Site.

Im Opening Tiltviewer in an Ifrage so my Navigation still is on Top. The problem is that this Navigation is featured with a Java Script Multi Level Drop Down Menu. This Menu works until I have a look on my Pictures. I think it still Drops down but BEHIND the Flash Programm...
what can i do?!
