--- Comment #1 from Louis Lenders xerox_xerox2000@yahoo.co.uk 2009-08-23 15:36:14 --- Created an attachment (id=23228) --> (http://bugs.winehq.org/attachment.cgi?id=23228) +winsock log, ran firefox for about 20 secs
there's a repeated warning warn:winsock:WSARecvFrom -> ERROR 10035, maybe that might give a clue?
