I think the horizontal navigation across the top of your page might qualify as prior art, if you had it up since 1995. As far as the frames-based content under your "Published" link is concerned, that must be more recent, since frames weren't around in mid-1996 (nor were tags in tables, as far as I can see from the w3c standard docs.).
I don't know about the DynaBook, but I agree that it's hard to imagine that the paradigm of persistent navigation was not invented before 1996.
