Is it kosher to accept your answer on your own question?

Recently I asked a question about Outlook Express crashing. Someone left an answer with a possible reason and a list of steps to do in case that was it. Turns out that wasn't it, and I discovered the reason myself while waiting for people to answer.

What should I do now? Leave the question unanswered and leave the answerer a comment? Answer it myself and accept that answer?
