Sorry, I'm not sure why or how that happened with the link.

The text boxes are definitely large enough. To better describe whats happening:
1. Quiz questions & answers pop up
2. User clicks answer, correct or incorrect is displayed
3. Next question is displayed, above process repeats
4. After about 3-4 questions, blank spaces & no questions or answers show up
5. Clicking 2-3 times shows the "correct/incorrect" displays but nothing else.
6. Then questions seem to resume and pick up right where they left off before the 'glitch'
Every single question does eventually show up so I'm thinking it's definitely not the size of the text boxes.
