To be exact, the top done button does not work on the TOC page in assessment preview. It works in the other preview screens.

2) Click Begin assessment to go to the TOC page.
3) Click the top 'done' button - nothing happens.
4) Click on an individual question.
5) Click the top 'done' button again - here it works.
