Hi, my client wants previous and next buttons on the slides, the player navigation controls have been disabled. I'm using markers on the screen. There are variables on the last of the numbered markers, changing the NEXT button on the same slide from Hidden to Normal. It works fine. However, when one then visits a previous slide (using the BACK button) and return to the earlier slide again, the NEXT button is no longer visible. Please assist, I need to present tomorrow.
