Apparently when I made Windows Pageant use the winselgui system, I added the call that gets WSAAsyncSelect response messages sent to Pageant's window, but I didn't add the switch case in the window procedure that actually handles those responses. I suppose I didn't notice at the time because no actual functionality used it - Pageant has never yet dealt with any real (i.e. Winsock) sockets, only with HANDLE-based named pipes, which are called 'sockets' in PuTTY's abstraction, but not by Windows.
