This has been happening to me with several versions on several systems. I share my project to a quicktime file. Then I make changes to the project and share a new file, replacing the original. Rather than writing a new file with the recent changes made, it simply makes a copy of the original file. I can always tell right away when this happens because the write time takes less than a second. There are obviously plenty of work-arounds to this, but can anyone explain why this is happening? Has anyone else experienced this? Is it a bug? This tends to only happen if I'm writing to the exact same original file (same name, format, and folder location) though it has happened when writing to a new location as well.
