Sorry you're having issues, guys. I wrote the site and tested under Netscape 7x, IE 6x and Firefox 1x running on a Windows box. I don't have Safari/OSX, so I can't test for it.
I'll be honest, though, it took *months* to get this site working right in the browsers/platform I did test on, so be patient, 'cause I imagine it will be a similar problem with OSX.
I have to say, if your box isn't running a new-ish (say last 2 years) version of whatever, you'll have problems. And I'm sorry to say, I just don't have time to make the site work for old versions of stuff (honestly, I don't think I *can* and have it still work in the newer versions!).
I'll look into the OSX issue.
Vicky - adding this to the list...
