IE 5 CSS bug: fixed?

I think I fixed the CSS bug that was causing my site to crash IE 5 on Mac OS X. The offending rule was for list items inside unordered lists inside the .navContainerSide class, which are specified as floating—apparently having floated list items breaks IE 5. I used the Comment hack to hide the offending CSS from IE 5 and it now appears to work. Please advise if you’re still having problems reading the site with a particular browser.
