Previously, the Check button was often shown disabled when it could not be used (e.g. when the question was finished, or when an interactive question was in the try-again state). Eventually we realised it was better usability to hide it in these cases. Note that when a teacher reviews an in-progress quiz attempt, they will see a disabled Check button if the student doing the quiz can see the button.
