Rule not automatically running?

Hi Guys,
I have many different rules on various folders all working fine, and I'm adding more all the time, now I have a slight problem with one folder where the rule is working fine but doesn't seem to run automatically, it works fine if I go and force a 'Run Rules' from the menubar or System prefs panel.
I've tried looking at the View log and can see many different folders being checked but this one isn't on the list.
I haven't changed anything with the rules on this folder, but have added new rules to other folders, apart from me manually disabling each rule on all other folders, is there an easier way to try and identify why this isn't being picked up automatically?
Cheers,
Paul.
