Enable/Disable a rule After you have created the rule it will be enabled by default. However you can choose to temporarily disable the rule by right clicking it and selecting 'disable'. A rule will have one of the following icons displayed next to the entry, depending on its current state: - When the rule is valid and it is enabled. - When the rule is valid but is disabled. - When the rule is invalid. A rule is invalid if a rule does not have any event ID's specified in the Event(s) page.
