Hello, can you send me the session file that doesn't work? If you'd like to keep the session private, please email it directly to me at gregc@…. Thanks. -- Greg

[Greg Couch]

Actually, I might have fixed it. Please test your session with the next daily build and let me know. The build will be dated 2019-01-17 or newer.
