Someone else has already asked a question about the exact same problem that I am having. Unfortunately, the question does not have an answer yet. Follow-on questions to the original poster have gone unanswered. How do I get an answer to that question?
I can't upvote the question unless I have 15 reputation.
I don't have an answer to the question (yet), although I do have some more information about my particular instance of that problem that may lead to an answer. I don't see how to just comment on the question.
What choice do I have other than to start a new post with the same question (and be responsive when anyone replies)?
