Hi, Frank,
if Strict Navigation mode is permitted in Next/Prev button settings then buttons will stay disabled until all time-paced objects of the slide's frame finish it's activity - please look at the Timeline panel. Or, if there are more than one frames on the slide, until all frames will be finished - look at the Frames panel (sometimes first frame set to wait for user action to advance to next one).
If Strict navigation mode is off, then the only way to disable this buttons - using NAVIGATION action or button's DISABLE method.
And, of course, buttons will stay disabled if there is no prev/next slide.
