No. You are wrong, it does not always auto save, as many have expressed in this forum..and also I have seen other websites discussing this same issue. I have done everything correctly with closing out iMovie properly. I have made changes to an original project, uploaded it from iMovie to youtube, closed out iMovie and came back to iMovie the next day...all changes made to the iMovie project the day before were gone. The project I uploaded to youtube had all the correct changes. So, Mac dropped the ball on this one by not adding a save feature. The auto save is faulty from what I have experienced and from what others have experienced. Apple has a reputation of being a "better'' standard in computers....this mistake is challenging it. The purpose is to not only make things "easier" for the customer, but also make thing more "user friendly", which sometimes mean allowing the customer to have total control of what they want to save.
