What I know of Windows and sockets connections: if it is not specifically and correctly programmed, a connection through using socket may stall the calling program if that connection is closed or goes nuts before the exchange is ended.

If this happens each night, then it's difficult to explain, but if it happens from time to time, this could be because of Poser calling home regularly

That being said: is there any reason why you haven't updated to the 12.0.703 version?
