I am curious on how it got there in the first place. Did you create a new project without giving it a name first? In Gloucester+ the ability to create a "no name" project now exists, and I am wondering if it is pathing it to the Global Audio folder as a catch all.
Not checked this yet, but I did create one of those and hit Ctrl-S out of habit, and "Untitled-1" popped up as the title. I guess I should go look for that guy.
Quick Edit: I just looked and do not see it, but remember when I closed that project it prompted me if I wished to save or not. I remember saying no to that, so it may have been eradicated at that point.
