Yep. The curious thing is I've been working on this for some time, and it's 
only just cropped up. Now it might be that I never did a revert with one folder 
like this before, but it might be something else that's changed. My first 
instinct, though, is that it's at my end.

Understood. I mention it to save someone asking, though.

One of the first things I tried was putting a breakpoint on -windowWillClose: 
The thing is, it doesn't get that far -- the breakpoint is never hit. That's 
partly why I'm unsure of where to look next.
