Can someone please advise re. SSM 189 - Preferences - Registry Keys - Uncheck the disable to edit box. How to then add new keys for SSM to monitor. I did manage to add one new key on one vacant line, but that was it - Any clues please re. how to continue adding - how to be able to move to a new vacant line - if it's possible ? Also, Under the list of monitored keys it says, $WATCH@n Block any changes of this key and n subkeys But at the end of each key line it has $WATCH@0 Is something wrong, or does n = 0 for some programming code reason ? Any help very gratefully received. Regards.
