Flash Horizontal Dropdown Menu Buttons Don't Work over DIV

Any suggestions please! I am a novice Flash Developer and I created a horizontal drowndown menu in Flash with rollover submenus. The dropdown menu has buttons with Behaviors assigned to "go to webpage". The published .swf file works fine, links and all. It is only when I place the menu inside a Dreamweaver DIV that exists over another image DIV that the buttons don't work. The menu will drop down and can be rolled over, but it is when I try to click on the buttons to activate the links that nothing functions.
It is worth mentioning that the buttons have an assigned "Down" state that doesn't activtate, so I know the buttons are incapable of even being clicked on. The problem is within Dreamweaver, not the flash movie menu. Perhaps I am overlooking a widely know trick to making this work? Am I missing a simple line of HTML??
Anybody have any experience with this?
Greatly Appreciated,
Lindsey
