If I fresh install the beta3, the preference saved correctly no matter I minimize or close it except using CMD+Q to quit the app. But once I upgrade the beta 1~3 from 6.11, the #1 issue can be reproduced 100%. For the #2, I believe that is a problem of sync.
I upgraded from 6.11 to beta 2 and then upgraded to beta 3. I don't know whether anyone reported these issues before. 1. Whatever options in the tabs of preference or in the right click menu, their values return to default once hide or close Evernote, even auto reset while I using Evernote. 2. It very easily auto-gens conflict notes somehow when I typing a long note.
