I did the upgrade, downgrade as well. Oh and turn off the check for updates as this gets annoying. My only worry now is if a security bug comes out against the 1.3 build as I'll be sticking with that version based on this new UI.
Agreed, I updated and immediatly downgraded back to the old version. Sadly I will stay with the 1.3 build until we can get an option for using the old good UI.
