Link Issues

Hi There -

Couple of issues. First, the links just don't work at all on Firefox - no hover behavior, no cursor change, no linking. They work in that they take you where you want to go in Safari, but there's no hover behavior or cursor change. I'm trying to address the links in the tabs using sIFR 2.0.5.

When I found the issue here - http://drupal.org/node/112533 - that described a couple of possible fixes. I tried removing the hover rule first. But each time I saved it, it came back to #666666 - there was no option to remove it.

I tried removing the underline when hover behavior, but that didn't do anything.

Can anyone give me any hint on how to proceed? This is a dealbreaker if I can't get it going.
