I asked this question about a month ago and opened a bounty on it last week. Of all of the answers given none of them correctly solved the problem so I never accepted one. Now that the bounty is over the system auto-selected an answer with 2 votes, instead of selecting another answer with 9 votes. What happened?
That answer was posted before the bounty was set, which makes it ineligible to be auto-selected.
You can see the rules surrounding bounties in the Bounty FAQ question.
