There's been a few answer posted to this one - all check the queue etc...

A quick, simple fix is to get the job to submit itself 1 hour (or whatever time
period later), then change the process to, say "News Skim". If the last job is
still running, this will error and you can do what you want at this point (like
stop 'cause the job is already set to run later anyway).

I know it not really neat but then it save DCL, checking of queues etc.
