Flash navigation question

Hello, im new here and i was wondering if someone could help me on something im having problems with.

i’ve made this flash navigation that is also loading a sound file, and when ever i click on a link, either in the flash nav or outside of it, the music reloads, even if i use my “turn off” music button.

so now im trying to use iframes to avoid refreshing the flash nav but its not really working. the flash navigation keeps loading with the page refresh, which im trying to avoid (maybe unnecessarily).

I have navigation elements inside the flash (of course) as well as sub navigation elements outside.

Any help would be appreciated. Cheers
