Logged issues don't get closed. At least, not until they get fixed.
The point of closing out old threads is that countless people find a solution to their problems and don't come back to report it. In order to have any hope at all of answering questions that people are still interested in, we need to clear out all of the abandoned ones. If we don't, it's exceedingly difficult to find the ones that just didn't get answers yet. We will gladly re-open any closed thread that a user is interested in upon request.
