1: Press control+windows+f2 and rename the session. 2: Restart Twitmonger.
Even though the new session loads, it's like I just created it. Every setting for the session is gone. It's like I reset the thing.
The old session's folder is still in the %appdata%\twitmonger folder, and I had to copy the session.conf file to the new session's folder to get my session back.
