When your question is closed as a dupe, but the original (by a different author) has an an accepted answer that is vague, dated or maybe not acceptable any longer (e.g. possibly the target technology has been modified since then) what's the recommended chain of events to go about getting better answers?
Is the bounty the best solution, maybe with a comment on the original question stating why you're posting the bounty? If so, how does the right solution get marked (or remarked) if it's not your question?
I've sometimes wished questions were versioned along with the version of the software they are based on.
