Slides won’t advance using the remote control, the keyboard arrow keys, the space bar, nothing you do advances the slides. advance doesn’t advance the slides!

Usually this happens after a break. Everything was working fine before, what happened? “How do I fix this?” is the better question.

The slide advances and all the other methods to advance slides work again.
