Problem changing state of Next button when returning to menu slide
The attached pic shows a menu slide where the pillars jump to their own sub-sections and the learner then returns back to this slide again, where the pillars change state to Visited. The slide is set to resume saved state, so that the audio commentary doesn't replay. When all the pillars' states are Visited, a trigger is set to change the 'next' button, (hidden at the start), to Normal. It does not work. Other events triggered in exactly the same way do work - for example, showing a layer, or making an object visible. If I preview just this slide, the next button does follow its trigger instructions and does become visible, but not when the page is previewed in context with the whole scene.
