2.2.1 on Mac has lost the menu bar
On my MacBook (el Capitan), OpenLP no longer shows a menu bar, making it difficult to do much. I use it mainly for setup and managed to tweet the core.view setting to restore setup view. I cannot see any setting that might hide the menu bar. If I go back to 2.1, or do a fresh install, there is no change.
