I have my firewall set to block all connections, and I have Vue set to not update or check from within the program. As I understand it, Vue doesn't have "network" copy protection, it uses the Vue4pro.eon file and the Vue4pro.reg file for verification. I prefer to get my updates from eon's web site. Of course I'm possibly a little paranoid, as I allow very few programs to access any DNS servers unless it's absolutely necessary for the program to run. Again, I'm not having any instability problems with the 272334 release, it's very stable even importing Poser PZ3's.
