And as a related issue, I've got a series of navigation
buttons on the left of each slide. Can someone please tell me how
to either:
a) add these buttons to a question slide; or
b) add these buttons to the background and still have them
work.
If you are referring to Question Slides, the answer is no.
One question per slide.
As for buttons on Question Slides, it's really not possible
to do. You probably already noticed that Buttons are disabled when
you are editing a Question Slide.
You can kind of add two questions by using Fill in the Blanks
type of question the draw back is you need both parts answered and
to be correct to score correctly.
If you are getting into Quizzes you may be interested in the
bug I have reported see eLearning in the Forum
