And then I worked 2 hours with LectureNotes , btw. I saw the ClipTray Box the first time in LectureNotes today as I copied text.
Saved, used DropSync and then rebooted. And no error this time
I denied the permission for the ClipTray with XPrivacy for LectureNotes, so I'm not sure if that was the solution or the Kitkat Update. I'm 80% sure it's the Kitkat Update.
But I will test the other option and report back.
Btw. does LectureNotes work with ART-Runtime?
