flickering in FF on Mac

[MacMajor]

If anyone here has a comprehensive knowledge of JavaScript and is also working on the Mac (FF only), please take a look at my test page with this menu and see if you can help with the flickering.

For ex. When your mouse is positioned over menu item and moved just a hair (or sometimes even when moving mouse normally up/down rolling over menu items, it flickers and jumps 2up (selecting it). If that makes sense. If you let your mouse sit a moment on the item, and then barely move it, the menu item (always 2 up) gets selected, but your mouse hasn't moved up 2 menu items, so I don't know why it keeps jumping like that.

Here's the page, and if you cannot reproduce the error yourself, I could take a screenshot or screen movie of the action.

Working between the Arrow Side Menu:

And the Glossy Accordion Menu:

I now have a working version:
http://macmajor.homeip.net/Menu/glossymenu.html

And here's the link to the problem version:
http://macmajor.homeip.net/Menu/arrowmenu.html

They both reference the EXACT same JavaScript files:
http://macmajor.homeip.net/Menu/js/ArrowSideMenu.js
and
http://macmajor.homeip.net/Menu/js/ddaccordion.js
and JQuery Link:
http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js

The CSS files are the EXACT same, except for the name of the menu:
http://macmajor.homeip.net/Menu/glossy.css
http://macmajor.homeip.net/Menu/arrow.css

The HTML is the EXACT same, except for the name of the menu.

Unless I happen to be overlooking something on the EXACTNESS, but I don't think so, because I checked everything with PageDiff in FF.

So Why on Earth would one version work, and not the other????

Would be nice to know, however, I'm just glad the darn thing works period.

Thanks,
Tracy

P.S. Apparently not a JavaScript problem as I was initially thinking.....
