I have a message that is marked "Ignore". It's a single message, not part of a thread. When right-clicking on the message header if "Ignore Thread" is ticked or unticked makes no difference, and the red circle icon remains : removing the tick by "View" -> "Threads" -> "Ignored Threads" always means the message disappears. I've tried using "k" to undo the "ignore" - that doesn't work either. I can't work out how to undo the "ignore" for this message, meaning I always have to have viewing ticked for ignore threads, which I don't want. How do I undo the ignore on this message?
