SYMPTOMSIf a Winsock application creates a window (hidden or not) to process connection messages from a non-blocking socket, the application may stop responding (hang) on the second connection attempt. CAUSEIf a Winsock application creates a window to processes Winsock messages for the connection, and the application deletes the window before the socket is closed, the application may appear to hang if it attempts to establish a new connection.
