There appear to be quite a few bugs in the firewall "Zone and Rule Setup" config box, one of which was identified as far back as Beta 2: 1. Sort by columns doesn't work (sort by application, trusted zone in, etc.). 2. Sometimes rules that are manually created don't appear in the list, and have to be added a second time before they will appear. 3. If an application creates a rule whilst the ESS GUI has the firewall config box open, the rule will not appear until either (a) next reboot, or (b) the GUI is closed, another window is opened (any will do, Windows Explorer for example) and then the ESS GUI is reopened. This bug was identified in Beta 2. I'm very impressed with 3.0.551.0 overall though! Very slick. Steve.
