FWIW, I can add another failure point to the mix. I spent all day one Saturday trying to come up with a workaround. It looks like this is one of the many cases where clever Microsoft programmers have worked around the clock closing up any loopholes which would allow useful behavior. Hmm. As I was typing this I had another idea which I don't think I tried. I'll look into that this weekend. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
