I've just added the Respondus Lockdown Browser App. The configuration looks good and I see the Lockdown Browser option listed in courses. However, when I try and enable the function for any quiz I always end up back with a "Fix It" button.
In the course / Quiz Options it doesn't appear that the additional quiz restrictions includes anything about the lockdown browser. The Quizzes are not locked in any way (super simple quiz).
Any help would be welcome....
