Here is the situation. I have a problem, and upon searching for a solution, I find that another SO user has already posted a question and accepted and answer. However, while the question perfectly describes my issue, the answer does not solve my problem.
What is the best practice in this situation? If I post a new question, it will surely get marked as duplicate, and rightfully so. If I ask follow up questions in the comments, I am potentially creating a cluttered, unhelpful comment section. I can upvote the question, but even if this gets more attention for the question, there is no reason for another user to try to answer the question, because the OP already has an answer he or she is satisfied with.
It seems like this is a situation that would arise fairly often because an accepted answer is not accurate or because there are subtle differences in the problem. As someone with a better answer, I can post that and get upvoted past the accepted answer. But as someone with the same question, do I have any recourse to get help from the community to find an answer that works for me, without posting a duplicate question?
