The way it was written was as a requirement:

"Requirement 3.2: the app crashes"

3.2 as a reason something is rejected ("app crashes") makes more sense. I wasn't sure if they're written it that casually, as it was quoted as such.

Yes, presumably that was in a section of reasons for rejection. It would be rather silly to assume there was a requirement that apps crash.

I believe it makes sense, in the context of Windows. They want users to feel as if they're in a comfortable and familiar environment.
