I've started to play around with Lightroom. I gave up on Aperture as it my mac really can't handle it. Its just too processor/graphics intensive! Anyway, I can't figure out a way to get pictures to show in full screen like in iPhoto. Not only is that a really great way to browse through the library (instead of building a slideshow), but its also really nice for editing. Does anybody know if Lightroom has this option and, if so, how to activate it?
