FYI: Two people used the Clicker today. There seem to be some issues where I have to manually advance into the Slideshow, then the clicker works. I think it's wise to advise the speaker to ask the operator to manually advance the slide if for some reason the clicker doesn't work as expected. My sense is that they may have to point the clicker at the receiver, or at least that there are some positions that don't advance the slide.
