Alpha Tester, Thanks so much for your response. I've tried everything so far, including this. But to answer your specific recommendation, I checked again to confirm my earlier efforts. Following the old adage, "it's not what you don't know that gets you, it's what you know that isn't true!" When I right click the BitSync tray icon only two options appear: - BitTorrent icon followed by the words 'BitTorrent Sync' - pin icon followed by the words.'unpin this program from the task bar" Checking the Task Manager confirms that BtSync.exe is running What do you recommend next. Does BitTorrent itself need to be running? I checked this as well, but am glad to check again. Any help or suggestions are welcome. This can't be as hard as it seems, so I know I'm missing something! Appreciatively, Tom
