Hi Darrel, Thanks very much for responding. I have since identified what the issue was. It was to do with transitions. I had several items (text box, exit button and background image) in a ‘Call-out’ group and a fade transition selected at the group level. As soon as I removed the fade transition at the group level and left the group as ‘none’ in the transitions – suddenly the ‘click to reveal’ action, behind the associated text mask, which displayed that particular group became repeatable. I’m guessing that this is a bug, as I don’t see why specifying a group level transition type should render an an action that shows that particular group, only able to be used in the first click instance. anyway, thanks again!
