In 220.127.116.11, I go into Toad Options->Network Utilities and edit a host in the top window pane. Works fine. I then attempted to move the FTP/SFTP column over, as it was scrolled off to the right, but the list of hosts was instead ordered by FTP/SFTP. I then attempted to edit another host, but a different one appeared when I clicked the Edit button.
I do have the same host with entries for both FTP and SFTP, if that matters.
