netscape4.x cannot read debian-user list archives

[Jan Krupa <krupa@alpha.sggw.waw.pl>]

I have installed netscape4.5b2 under debian2.0.
 When I try to read debian-user mailing list archives 
(e.g. from September, august) first
time it's O.K. but next times on the same month archives
netscape just hangs I have to kill it (the archives are very big).

 When I try to read much smaller archives (e.g. debian-changes,
September) it's all right.

I had the same behavior using netscape4.x, but netscape3.x
reads the archives well. 
 
Does anybody have any idea  what causes such behavior of netscape ?
 May be I have configured netscape wrong. 
 My be I some hint what change in preferences?
