I've just installed 6.1, and it fixed a lot of problems, but also added one... all of my Favorites (though they still work) now have this: "$ chr(35) $ +" in front of their names (e.g. "$ chr(35) $ + GameMusic", instead of "GameMusic", and the "Join All" option displays as "$iif (((1))) and server, [...blah blah...],Join All".
I'm using the PnP (Peace and Protection) addon, if that's of any importance...
