By inserting a Click Box, Button or Text Entry Box object on the slide.
Thank you, I already have click boxes and buttons on every slide - the slider at the bottom still automatically moves, it doesn't go to next slide until button or box is clicked. I want to stop it moving if possible?
Update: looks like it does the same on the old versions - I'm assuming its the time set to play each slide. I will just even these up so the don't look so inconsistent.
Perhaps you need to move the pause points for the interactive objects to be closer to the beginning of the slide?
