Once Unity loads (Web player) how do I prevent it from being *Focused*?

I have a unity web player running on my blog, but once it finishes loading (with the assumption the visitor is scrolling, viewing other items) the page stops scrolling, focusing on the Unity file (movement of mouse relates to the file of course, but since the user is half way down the page they have to click out again (sometimes unknowingly)).

I hope it makes sense, it's a very small thing, but I want the user on the otherside to flawlessly move around the page. Thanks.
