Some of the effects here, such as the alternating message backgrounds, are done with CSS1, which is buggy in Netscape 4. Bug activation in Netscape 4 has been minimized, but wrongly sized boxes is one I can't duplicate. My advice is to leave Netscape 4 behind and find something newer: e.g. Netscape 6, Opera 5, Mozilla, IE if you can stand it.
