Microsoft PowerPoint 2010 AutoSave Doesn't Work, Even With Some Crashes

Unfortunate news: even if you have the autosave option turned on, PowerPoint isn't really making an autosave document that will persist after all crashes. Even worse, if you exit, and it tells you that if you don't save, you'll still have a draft, you won't actually have a draft. PowerPoint seems to delete its temporary files when you exit the program. When I tried to kill PP, it still deleted the file. So that bit of cleanup code is pretty resilient, at least to my half-hearted effort to blow away PP.
