I don't know if my issue is related to MDL-35754 but If I select 'Browser security' to "Full screen pop-up with some JavaScript security" the quiz doesn't open. The confirmation dialog box pops up but when I click on 'start attempt'the quiz is not displayed.

In top debug mode (developper) mo error messages are displayed at all.

I'm using Moodle 2.3.2+ (Build: 20120927)

I can reproduce this issue in Firefox, Chrome and IE. @moodlerific also reported me by twitter the same issue

FULL STEPS to reporduce this issue:

a.- Setup a Moodle Quiz
b.- Select 'Browser security' --> "Full screen pop-up with some JavaScript security"
c.- Save the quiz
d.- As a student try to open the quiz --> The quiz doesn't open
