tanstaafl, use the tracker status column to find which ones have a problem. The problem with showing the red icon is that for 99.9% of the torrents, it says there's a problem when there isn't actually one. DHT is more than sufficient to find peers. Hell, for a lot of torrents still floating out there, the tracker's been gone for ages, but the torrent is still very much alive. It should probably show it regardless of how many peers you have for private torrents, though.
