Thanks for the heads up and sorry for the inconvenience, Goaldeje. Exterminating that elusive bug is definitely on our offseason To Do List.
FWIW, when we customized the Flash header and replaced/expanded those top navigation buttons, somehow we lost a line of code (maybe added one?) when the programmer we hired did the actual re-install that affected their operation in some browsers.
We're going to track it down though. We're relentless.
Question for you, if you don't mind:
On some browsers they won't work when you first come to the site the first time in a fresh browser window, but then
will work after you've been to at least one other page. Is that the case in Firefox for Mac?
