I just found out how to "fix" the problem on my Evernote (126.96.36.19927 (307027) Public (CE Build ce-43.0.4829)). So i experience the same problem as the users above have described while tabbing back and forth between VLC and a note... losing focus became super annoying... so I "decided" to try hiding the "Note List" by pressing F11 and now everything works fine. I discovered it, sort of, by accident. Hope this can help people that don't want to or cannot update to the beta. Good luck Edit 1: Just found that my solution doesn't always work. So I experimented. In the "Note List" make sure you have no search words or tags selected before hiding it. The note list should just view the notes in your selected notebook. If this doesn't work open the note in a new window and close the main window.
