Static Flash Menu with changing html page

I’ve read several older tutorials but need a modern approach to this.

I want a flash menu in an absolutely positioned div that loads html content in the same window. I want the flash menu to be static and not refreshed, but only the html content changing.
I do not want to use frames, but I am wondering if javascript can be called through flash to do this.

Can someone give me a relatively easy and modern way to do this.

Thanks
