Okay, when I stopped the 'Logitech Process Monitor' service the problem goes away. Thanks for the quick diagnosis. I rebased the camera dlls but that does not fix this problem. Can you tell me what the root cause is? Is there any way to prevent this problem? I.e., the problem of "foreign" dlls causing cygwin forks to fail? cheers, John -- View this message in context: http://www.nabble.com/1.5.21%3A-fork-in-find-ls-failing%2C-simple-test-case-tf2197641.html#a6087159 Sent from the Cygwin Users forum at Nabble.com. -- 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/
