ive set it several times as my default, but every so often LimeWire resumes as the default downloader. i uninstalled LimeWire, but even so the site im downloading the torrent from doesn't ask me if i want to use BitTorrent. i know i can save the torrent and then open it through BitTorrent, but id like to set it as the default so i don't have to go through that every time. what do i do?
