Next button on quiz slide not appearing until user clicks anywhere on screen after correct/incorrect text appears?

I suppose you are using a version before Captivate 9, is that correct?

Question slides have very strict rules. They have a lot of embedded objects (they don't have an individual timeline) that you have to be careful about. The Next button - until Captivate 9 - has a double functionality in your version:

• During Quiz it is meant to skip a question
• During Review it is necessary for navigation, then it is a real Next button.

If you don't use Review, you can uncheck the Next button in the Quiz Properties, you don't need if you want the user to answer each question.

The most important button is the Submit button, that triggers the two-step submit process:

1. User submits, the feedback appears with a warning to press Y or click on the slide after they have read the warning; that first step is not releasing the playhead which remains at the pausing point of the question slide (default is set at 1.5secs, but can be changed). If the Retry caption/shape appears, he can retry the question until the attempts on Question level are exhausted.
2. User clicks on the slide or presses Y: now the playhead is released and the action specified for Success or Last attempt will be done (default is Continue).

Next button shouldn't be used in that process. If you really want to have such a work flow, you have to cheat on Captivate: create an image or a shape that looks like a Next button and put it on the question slide, for SWF output this will work because when you click on the 'Next' image, you click on the slide as well. For HTML output this can be difficult, because an interactive object is not always active when it is covered by a non-interactive object (the Next image).
