When does MacJournal save my data to my hard disk?
The rule of thumb is that when a save is automatic as part of another action the data are not written back to disk. So when you change entries while you have unsaved changes that’s an automatic save so the changes wait until you manually save it or you quit. The Save button and menu item are enabled when you have unsaved changes in the entry you are currently working on. This is somewhat different from when the data in memory are different than the data on disk. Note that the data are also saved back to disk when the Auto-Save fires for however often you have it set. So you can set up the auto-save interval to save the data back regularly and if you ever want to do it right away you can make a change to the current entry and then hit save.
