I'm running two displays not mirrored. I'm trying to run Keynote on the projector display and Ableton Live on my laptop display. How can I show a Keynote slide show on one display and still use Ableton on the other display? Keynote Preferences - Allow Dashboard, Expose', and others to use screen isn't working. It only allows you to run the dashboard on the presenter display, but not view another app. Presenter Display preferences are all unchecked. Even with this, the presenter screen is just black - very helpful. :b Is there an app somewhere for allowing this? Also, I have to be able to run the slide show because it includes streaming video and I want the transitions. I don't want to just "view" Keynote on the second screen. Much obliged!
