On a RMBP running Yosemite, Keynote updated to the latest version on the App Store.
On opening a keynote presentation created and run successfully months ago, when I play it, I get only a blank screen. If I hit the space bar a few times and hit ESC, the presentations appears to have been moved up that many slides, but nothing shows on my laptop.
I don't have any external screens attached, so while I suspect something thinks there's an another screen and is trying to project to it, I can't fix it.
I've tried rebooting, no luck... any ideas? Thanks!
