Dropdown menus are "stopping" my Flash animation, causing choppy animation. IE ONLY

Background:

On a recen开发者_JAVA技巧t website, I'm using a jQuery driven dropdown menu in addition to a Flash scrolling animation.

Note: I am only using the Flash animation in IE only as I created an equivalent, jQuery based animation for all other browsers (because, surprise, IE didn't handle the jQuery version). So please look at this in IE only.

The Problem

When you hover over the dropdown menus, the Flash animation temporarily "freezes" and the continues. This causes choppy behavior in the Flash animation.

Questions

1. Whey is this happening?
2. Is there anything I can do to stop this behavior?

Try adding the wmode="opaque" parameter to your movie object.
