They should fully test service pack 3 before releasing it...
It would be nice to have a clean install the first time, but that's what you and I are for.... Well let's not be too hard on them. Bet they really do try hard, however, after all they probably use about a million lines of code! Bound to be some issues.

I also found that the service pack 2 firewall conflicted with other firewall software in some cases
That could be a problem with any combination of firewalls of the same generation. They're both trying to do the same thing at the same time

cheers
