First I try the "icosa" link in the navigation-bar above: this gives a scrolldown menu; I pick out "articles" (btw "new and rare" or "German catfish-scene" etc give the same result).
clicking this gives me: "error 404" file not found.
without clicking anything iit changes back into the page seen as
http://www.planetcatfish.com/core/index.htm
except now I have TWO navigationbars stacked on top of each other.
clicking on 'icosa' in the center-right of the screen (3rd column; 2nd from top) or on the black-and-white arrow-button in that same square (the one with "Focusing on the catfishes of this region, Ingo's Catfish of South America features a huge article on breeding L-numbers"-text in it), results in the same.
first the "error 404" message; then I get directed back to the mainpage and a second nav bar is shown.
If I repeat this I can get at least 8 (!) navigation-bars, and an empty one; after wich the page crashes and a blank screen shows with "done" (or "free menu applets at
http://www.apy.com") in the lower left corner.....
My browser is Firefox 0.8 (1.0 has way too many glitches and bugs yet) by Mozilla, but it has worked perfectly until now.
