I noticed this problem yesterday. Every time I quit Logos 7 it hangs on the synchronization. I have to quit it to get it to end. I have included two logs below. Thanks for your help!

This is simply additional information about my problem. When I started Logos 7 today, I noticed that the synchronization process runs for an extended period of time (at least 5 continuous minutes) and then the red exclamation point appears in the middle of the circle.
Are you using the new Notes Tool Beta?
