I agree that it's frustrating (also happens to me all the time) but would argue that it's stackoverflow's fault. They are, after all, supposed to curate the content to make sure it stays relevant, up to and including deleting questions. At the very least it should be easier to get the accepted answer chenged so at least it's at the top of the page (I can't be bothered to spend enough time gaming the system to get the 2000 points necessary to do this).
