This happened after I was replying to an email and part way through Windows switched the active window to Thunderbird from the Compose window. I clicked back on the Compose window, finished my reply and sent the message. Only then did I realise the display had the sub-folders. I assumed my typing had activated an option, which could be reversed through one of your menus. Sadly this does not appear to be the case, How can I remove these sub-folders and revert to a straight listing of messages? Reproducible: Didn't try Steps to Reproduce: 1. At the moment this is a change to my system which I cannot undo. 2. 3. Actual Results: n/a Expected Results: n/a Only the inbox has been affected, This was the active folder at the time the problem occurred.
