Uh, so I knew that Word would save copies of my open files, and firefox would reopen my session and tabs on a crash, but when did textedit start doing that?
I have a bad habit of keeping notes in textedit (stickies started losing data on me) and not saving them. I just had a kernel panic, and when I rebooted and reopened textedit, all 5 unsaved files I’d had open popped back.
