Printf goes to a buffer, which is not necessarily flushed until you do input using a stdio function, or explicitly call fflush(stdout). Generally speaking, if you have started curses, all your output should be done using curses routines, so that the curses library knows about it, and does the right thing for refresh, maintaining the current cursor location so the next printf() goes to the right place, etc.. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
