Devonthink is acting weird on my machine these couple of days. It revives itself randomly after quitting the app. I double checked the activity monitor after I quit to ensure the process is gone. Did a couple of shut downs, didn’t work.
Not a big deal just a confused user.
Are there any folder actions or other scripts or e.g. Hazel rules which might launch DEVONthink 3?
Now that you mentioned other than the inbox in Finder, I do have Tinderbox watch a group in DT.
Perhaps I may have jumped the gun since I stopped encountering this behaviour today.
