Yeah, I’m not too happy with the latest revs of Commodo Firewall, myself. Nothing as bad as what you faced, but it’s been way too sensitive to everything.
It gives me 3 to 5 warnings when I try to open any app. After struggling with that for a couple of weeks or so, I finally just set it to ignore any apps starting up. Not the ideal solution, but it was bugging the tar out of me.
Was this a failure of the functioning of the package or just one of those ....installation problems....?
