It also keeps complaining about this while browsing the newsgroups:
err:msg:PostMessage16 16-bit message 0x000c contains pointer, cannot post

err:winsock:WS_setsockopt Invalid level (-1) or optname (128)
err:winsock:WS_setsockopt Invalid level (-1) or optname (128)

None of this affect using it as a web browser in any way what-so-ever.
