It appears to be a problem specific to Netscape 4 (I haven't bothered to determine which versions specifically.) Mozilla (aka Netscape 6) seems to cope OK,
as does Intertnet Explorer (unfortunately) and the excellent Opera (which I thoroughly recommend: version 5.12 is great, they managed to break a couple of things in 6 but I'm sure they'll get fixed soon.)
HTH,
