Flash Inside HTML Page

I created a Flash header with animations and buttons for my HTML page. The Flash movie loaded fine and the animations work when I view it using IE. HOWEVER, in order to be able to start clicking the buttons, I must first have to click on my movie once. Why is it doing this?

I found a good example: http://www.ochealthinfo.com/ Notice the animations work, but if you point your cursor at the animation, you much click it once, then click it again to go somewhere. Is there a way to bypass the first click?

Thank you.
