Do you find this text in OverbyteIcsWSocket.pas?

{ FP:26/09/06 Are FD_READ and FD_WRITE really necessary ? Probably not ! }
{ Lodewijk Ellen reported a problem with W2K3SP1 triggering an AV in     }
{ accept. Keeping only FD_ACCEPT and FD_CLOSE solved the problem.        }
{ Anyway, a listening socket doesn't send nor receive any data so those  }
{ notification are useless.                                              }

Sounds like the same problem.
