Help! I was using Keynote to make two presentations today - the first was fine. The computer was turned off for a couple hours, then I turned it on to do the second talk. I clicked "play" and the first slide appeared on my computer, but on the screen we saw what you see when you click "rehearse slideshow" - two windows and the time that has elapsed. No matter what I did, including restarting the computer, this kept happening. I had a CD of the same presentation in powerpoint with me, so we put that on someone else's computer and I went on with the talk. Any ideas? I'm worried that this might happen again. THANKS!
