Safari MegaMenu c/ hoverIntent problem when rendering over Flash swfobject

Question

I have a bizarre problem that recently surfaced. I have some megamenus -- they are coded very simply as unordered lists and use jQuery. There are coded up very much like this SitePoint tutorial found here.

Here's my jquery

$j('li>a[topnav], li>div[topnav]').hoverIntent({
    sensitivity: 4,
    interval: 100,
    over: ShowMenus,
    timeout: 0,
    out: HideMenus
});

We're using the hoverIntent plugin to control the onhover, and offhover events. On our landing page -- we have a flash movie (embedded with swfobject.js) and the megemenu is supposed overlay it -- which is does. But, unfortunately -- when the menu opens, all of my menu items collapse in Safari. You can see this effect only when using Safari 5 at Greenmountaincoffee.com. When I remove the flash animation, the menus work fine and do not collapse.

Has anyone encountered this problem before? Any strategies recommended?

Thx
