Thanks guys - yes. aware of the path requirement but it's not starting, afaik, so it doesn't need to stop :-)
As for the scheduler, yes, that's what I'm using as the alternative, but if it doesn't work for Deluge, it won't work for any other programs.
I'll check that crond is up and about.
ps -ef | grep cron gives
$ ps -ef | grep cron
root 1119 1 0 Nov14 ? 00:00:00 cron
Stephen 5743 5623 0 20:38 pts/1 00:00:00 grep --color=auto cron
Maybe it should be sudo crontab -e ?
Given that the stuff above means it's going - I've tried the sudo command, so see what happens tonight my time.
