I'm building a website for work and the spry menu bar looks and works great, until I look at it on a Mac. It looks fine on any browser on any Windows machine, but as soon as I switch over to the Apple, it jogs the menu bar to the right and pushes the last menu button below and to the left of the rest of the menu bar. It does this on any Mac I've tried, in both Safari and Firefox. I can't for the life of me figure it out and its driving me crazy. Any help would be greatly appreciated.
Thanks,
Art
Here's the website and CSS:
