macos sierra 'chess' covered by incomplete message
Following a clean installation of macos sierra I fiddled around with some of the preinstalled programs. Some seconds after starting a new game of chess the app 'opens' (better: starts to open) a message window but doesn't display any content - and freezes. I can open new games in new tabs but can not close the game I started first and can not close chess as well other than killing the process. The issue persists after deleting the prefs-file in the library folder, after various reboots and even after a reinstallation of sierra. As a 'system app' chess can't be deleted / de- and reinstalled...
Any hints are very welcome...
