In Captivate 5.5 it defaults automatically to Go to next slide.
Too bad, Click boxes have no style, and the Action cannot be applied to all click boxes. Was just wondering if changing the timing to 'Rest of Slide' will not give you the same functionality? Timing can be applied to all click boxes. Continue in that case will just proceed to the next slide, since the pausing of a click box is always at the end of its timeline.
