Thanks for the answer. There is indeed a status bar at the bottom of the edit window, but there's no "plain text" choice, only "textile", which I selected.
If 'Plain Text' is not in the drop-down then you have disabled the 'Text' bundle.
Goto menus: Bundle->Bundle Editor->Show Bundle Editor, at the bottom of the window is a button labelled 'Filter List', in the list make sure to tick next to 'Text'.
