When a torrent in transmission is in error there is a red message which displays above the progress bar on transmissions web client. On the transmission web client, if you view info on the torrent, it has a message under the "Error:" category. It doesn't appear nzb360 displays this error message on either the torrent or the info panel that slides from right to left upon clicking the torrent. Not sure if this is truly a bug or a feature request. Thanks for the great app!
