What was (or at least at the time appeared to be) a [correct answer](https://apple.stackexchange.com/a/48412/4395) to a [question of mine](https://apple.stackexchange.com/q/30977/4395) is now (possibly due to software changes by Apple) no longer resolves my question. I've already accepted this answer as the correct one. How should I handle the fact that what it suggests no longer works? 

Should I un-accept it? Is that sufficient?
