Links not working on Firefox/Mac?

[mhanson]

I have a somewhat odd problem. I built a site - www.ipms2012.org - and it tested out fine on the PC and even on Safari/Mac. Then I got reports that it wasn't working properly on Firefox/Mac. I installed Firefox on my wife's Mac and sure enough, the page displays fine, but the links on the menu bar don't work. The cursor changes, I get the right link in the status bar, but nothing happens when I click them. If I right-click and select 'open link' it does work.

It works as designed in Safari/Mac, and in Firefox/PC.

I'm open to any suggestions.

Thanks.

Mike
