I'm sorry, that I didn't reply for so long. By saying "stops downloading host list" I mean, that at the bottom gnutella has number of servers that can be stored in cache, and the number of servers acrually stored. When gnutella starts, for few seconds number of servers in cache is rising (to about 10 - 20) and then, after few seconds cache becomes (and then stays) empty.
Now I don't have gnutella instaled, I'm using other client which works well. Maybe I will try it another time.
Thank You very much for Your time.
P.S. Sorry for my English.
