I'm not too fond of the latest incarnation of LiveZilla. The most recent update released in April blocks the last quad of an IP number from operator view. Also, there's some flood filtering installed which can't be undone.
Why this is bad? When a user comes to us asking if their IP is blocked, we were able to look it up quickly while they were in chat. Now they have to go to a website to find out their IP so we can look it up. Time consuming for the technically challenged user. The flood protection, while a nice feature under normal conditions, unfortuatnely means if a user can't connect for whatever reason and repeatedly hits the Live Chat option (lets say they're getting dropped due to poor packet connection from Asia) - it automatically thinks they're trying to flood the Live Chat with requests and blocks the IP nubmer in a permanent ban list. The client must then open a support ticket complaining that we blocked them from live help, and we then must unblock the IP. Previously, this was not automated, and allowed our staff the option to ban an IP if it was needed, but with 100% automation, it's not good.
I'd downgrade back to the older version, however there were some security updates in the new one that are needed. Hopefully they make some edits on their new release when that comes out.
Good program (could use the option for server operators to log out other server operators if they're not there) - currently if "bob" logs in and doesn't know it, there's no way to log him out. Talk about a PITA when the guy is gone for the weekend and forgot to log out of chat!
