I've noticed that ESS creates seperate entries in the application list for an individual application, depending on whether you create it manually or from the interactive mode pop-up. I created the following rule manually by entering it in the 'Zone and rule setup' section of ESS. Make a note of the filepath. Then I opened up iTunes and interactive mode popped up because iTunes wanted to use UDP port 5353 for library sharing, so I created the following rule. You would think that this new rule would be tucked away neatly beside the 'iTMS' rule I manually created? But no, it has its rule added under a new 'iTunes' entry. ESS seems to create different application entries because when you create a rule manually it sees the filepath as C:\, but when you use the interactive mode pop-up it sees the filepath as c:\ I know it's only a minor thing, but for the sake of neatness it'd be nice if every rule created for a particular applictation remained under a single application entry. I hope this has made sense to everyone reading.
