This happens if I do a reinstall from the backroom or if I re-run the package installer on the client. After the client is updated to 6.3 the screen is black when I try to reconnect. If I restart the computer, everything comes up just fine. I've been going to menu: Miscellaneous...Reboot and Reconnect...To Normal Mode. I've updated 20 clients so far and it has happened to every Mac client so far (about 15 of them). The PC clients work fine. The version I'm updating from btw is 6.1. I have a lot more to update, but thought I would hold off until I heard back.
