windows xp, actual (SP1, all bugfixes)
thunderbird 1200
geforce2ti
256mb ram
same problem, when i add a server to the field but with no server there is \"timed out\" or something like that. that means, the buttons works, am i right?
edit: i meant the \"server dropped us for unknown reason\" error
edit2: compatibility mode activated for win98/me, but still doesnt work

are the servers too slow or is this really a bug?
