PC Tools Firewall Plus is bugware like OA fw. 
Actually pctools firewall is very good in my trialing of it, standard install with nothing touched and it passed all my tests 100% and was probably the lightest firewall iv ever tried, is also now owned by Symantec.
The only person that would call OA bugware would be a zone alarm fanboy who obviously has no real idea about a good firewall, rdmaloyjr you praised ZoneAlarm to everyone and it was the best thing since sliced bread but now you've moved on to unrated FortKnox

craigb,
I haven't moved to FortKnox fw, I'm just taking it for a test drive. Maybe I will if I like it enough.

Sometimes I like to try out other software.
PC Tools Firewall Plus is the second most used by me. OA may be the third most used by me. I don't live in the past, sometimes I retry software that I've used before.
I liked OA, but it's just too buggy. I really liked Privatefirewall a lot. I hope they get it right.
If so, ZA will have some good compitition. Privatefirewall will have the upper hand as Privatefirewall has good support.
For now ZA is the best fw.
