I only see the Labels option for individual torrents that are on my list when I right click on the torrent. If I select Hidden, that torrent disappears from the list. I am using 7.8(build 29545) [32-bit] on Windows 8. Before I upgraded, when I selected a torrent magnet from a site, a dialog box would appear while the system loaded the torrent information. Once the information was populated I could select Ok and the system would add it to my list of torrents in the main window and begin downloading. Now, when I click on the magnet, no dialog box appears, nothing gets added to the list in my main window, and nothing gets downloaded. However, if I select the magnet for the same torrent again, I get the message that "The torrent you are trying to add is already in the list of torrents. Do you want to load the trackers from it?"
Regardless of whether I select yes or no, nothing happens. I uninstalled BitTorrent, purged all torrents and reinstalled, bit I still get the same result. It hasn't worked for over a week now.
