No "patches" for any NS, best bet is upgrade to Mozilla 1.6.
where has netscape hidden the cache file in this version? I like to dump/empty it out once a week if not more often...not sure where to look for it....also -are there any 'patches' for this version? it seems to be crashing for no apparent reason.....at least once a day....
