XF 2.1 How to disable bbcode editing with text code

[Mr Lucky]

I'm often getting users telling me the image icon is greyed out. It's usually because they have inadvertently clicked on the cogwheel and just have text code editing mode.

Is there a way to disable this? I'm aware I can remove the cogwheel icon itself, but then any user who has already clicked it will not be able to turn it off and be stuck in bbcode limbo forever.
