Tried it right from the top of the site (home page.) and it doesn't come up. I'm currently testing the Firebird browswer from Mozilla, plus using IE 6 SP1 and Mozilla 1.4. It doesn't show up on Firebird or Mozilla even though, as I stated, neither brower has trouble with them on any other sites.
You may want to test it using Mozilla, which is just the unbranded version of Netscape. You can get the software here http://www.mozilla.org/. If it doesn't work on Mozilla or Firebird, then chances are that it won't work on Netscape either.
