I am currently downloading a file from a website and downloading multiple torrents. So I know there is traffic. However, Comodo doesn't show any traffic.
Summary > Traffic section is blank (empty). System Tray Icon Animation is enabled, but none is shown in the tray.
Firewall > Common Tasks > View Active Connections shows zeroes (0 B) under "Bytes In" and "Bytes Out" for all the listed applications:
Comodo Free 3.5.57173.439, with Network Defense Enabled.
Vista Business SP1
Avira AntiVir Free 18.104.22.1687
Note: Microsoft Network Monitor is not installed on my system.
