Hi David. Without knowing what "scap" does, I can't be sure what it's supposed to do. Keep in mind that cron doesn't have the majority of the environment variables that an interactive shell session will normally have, it could be that scap can't run successfully without one or more of them. If, as the name seems to imply it is a screen capture program, then it probably doesn't have the "DISPLAY" environment vaiable set, or for that matter have permission to access $DISPLAY even if the variable is set. Try dropping in another temporary entry in your crontab to run "set > /tmp/cron_env.txt" to see what environment SCAP is trying to run within. Or add "> /tmp/scap.debug 2>&1" to the end of your crontab line to capture any outout and error messages.
