--- Comment #11 from Damjan Jovanovic damjan.jov@gmail.com --- Created attachment 66124 --> https://bugs.winehq.org/attachment.cgi?id=66124 WSAAsyncSelect FD_WRITE hack
This hack makes WSAAsyncSelect() work more like it used to before. The results should tell us where to look further. If it helps, the regression is in WSAAsyncSelect(), otherwise it's in WSAEventSelect(). Please test.
