I need to have my slides set to be a specific length of time (the whole course has a time requirement). I already have the slides set to not be able to click 'next' until the timeline is complete. However, I do want to have the seekbar or something showing progress of where they are on the slide timeline, but I have discovered that you can click in the seekbar and speed up the timeline, which I cannot have the user be able to do. Is there a way to do this??
