Not quite sure. There are so many things you could look at. Have you added anything new lately? There is a lot going on , using several scripts and some dhtml and CSS. In Netscape the dynamic animation does not come through. I an viewing this on a 17" monitor at 800x600 resolution and there was a scrollbar at the bottom. I scrolled over about 3 pages worth and saw nothing. This is going to both annoy and confuse viewers.I would consider maybe rewriting this page over from scratch and see if that helps. Make it Netscape friendly in the process.
