Keynote hyperlinks
I've set up a presentation with the first slide as a contents slide with each of the presentation categories in a list. Each item is a link to the first slide in that category. The last slide in each category has a link back to the contents slide.
This works exactly as expected on both my Mac Pro and MacBook Pro when either played or using Rehearse but when I connect my laptop to a projector, clicking a link just transitions to the next slide i.e. if I click the link to section 8, when not connected to the projector it will jump to section 8 but when it is connected to the projector it just transitions to section 1.
