Keep in mind that articles can remain available on the server for a period
as short as a few days. If you mark an old article for download the news
server will reply that the article is no longer available, and as there is
nothing NewsHopper can do once the server says so, the article reference
will be deleted and of course no new article will appear in the newsfile.
There has been absolutely no report of NewsHopper crashing when such a
scenario happens. This could easily be tested because of a bug in NNTPd
that causes the server to sometimes reply that _all_ the articles are
unavailable.

If the articles you download are still on the server (the "Bytes Received"
count is more than a few bytes per article), they are immediately saved in
the newsfile, so maybe you use some kind of SCSI driver software that
caches a lot of stuff in memory.

Have you increased NewsHopper's memory partition ? With a newsfile that
big, you will need to allocate at least 3 or 4M for NewsHopper.

NewsHopper 1.1, scheduled for March, will come with a new manual, and will
be available free of charge (electronically) for users having purchased
1.0. The demo version will also be updated to 1.1.
