Thanks for trying to fix it and for > responding to my post. Too bad. Since I can't duplicate the problem it will be difficult to fix it. It would be helpful if you provided more information like the cygcheck information requested in http://cygwin.com/problems.html. It would also be interesting to see the actual file sizes of foo and bar from your example. If they always vary in a consistent way that would be a clue. 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/
