--- Comment #10 from Kai Blin kai.blin@gmail.com 2008-05-25 04:02:21 --- Reading over the the original +winsock trace, everything _looks_ ok. There's data transferred just fine.
However, as in the minimal example I posted a trace for, there's a "closesocket" after the "bind". No idea what's going wrong there.
