I have an unusual one at the moment. I've completed a fresh install of Ubuntu 16.04 and OpenPHT on our media center desktop. Running the latest version of Plex Server on another computer elsewhere in the house. At the end of watching an episode or movie, it will often just exit OpenPHT instead of returning to the episode/movie selection screen/OpenPHT interface.
Had a quick Google but not finding much info. Wondering if anyone has any ideas as to why this might be happening?
