I asked this question, which turned out to be a duplicate. That's fine, but the dialogue I was presented with is suboptimal:
Why is that a problem? Because the other question has no answers (at this writing). So it didn't solve my problem; it just connected me with somebody else who has the same problem.
Should we reserve "that solved my problem" for questions where a solution at least possibly might be present? In this case, something like "yup, that's the same question" would have been more appropriate.
(I think it used to be the case that you couldn't propose unanswered questions as dupe targets. Maybe that was true when this dialogue was designed. But it doesn't seem to be true now.)
