It didn't affect the behavior in either case >(service not started with the swap; no output from ssh without the swap). Any and all combinations are welcome at this point. There seem to be an infinite number of straws. Next straw would be to put a call to init_console_handler(TRUE); just before the call to CloseWindowStation: if (horig && h && h != horig && SetProcessWindowStation (horig)) { set_console_handler_true (TRUE); CloseWindowStation (h); } >> Also, what version of XP are you running?

Maybe that is a clue, as Yitzchak suggested. I'd missed that in the cygcheck output. I'm running SP2 and I believe Corinna is also. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
