When "Hide the Navigation Bar" is selected in Display Settings, the Library Backup function no longer works. I can choose the location for the backup, but when I select "save" the file name and save button disappears and nothing happens. I remembered I made a few changes to the Display Settings and did some troubleshooting to determine that was the culprit.
