How to disable automatic spell checking?

Hi finwe,

Thanks for getting back to us. Sorry for the conversation split here. I've had a look back and can see that all other reports of this spell checking behaviour have been included for our Product team.

With your main language set to Czech, I can understand that this behaviour is not desirable. I've also filed your feedback with our Product team.

Please let us know if you have any other questions.
