After upgrading to macOS Sierra, and iOS 10 on the iPad and uploading latest versions of Duet Display, what was working seamlessly is now problematic. E.g. Cursor as it goes from Mac to iPad becomes huge Window dragged from Mac to iPad goes black until fiddled with Some text becomes white-on-white Some window borders break up Exiting duet on iPad can leave Mac thinking windows are still on iPad Evidently something is amiss. Just me and some simple solution? Or a problem with Duet Display??
