@reduz on Windows it works, but on MacOSx the editor freezes on finish, the last console output is:

Re-run with the -verbose and -certs options for more details.

There were indeed issues with EditorResourcePreview which have been fixed recently, so I think this issue might be fixed in the current master branch.

Please comment if you can still reproduce it in 3.1 beta 2 or later.
