It's because you are not running the program with stdout attached to a terminal or terminal emulator. Probably, you are running in a console window. Cygwin can emulate a terminal in a console window for programs that do all I/O through it, but for third-party applications, like Sun java, it cannot. Run the application in rxvt and it works as expected. -- Barry -- http://barrkel.blogspot.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/
