Love this app, like the look of it, like the functionality, like the price, and I'm desperate to give it five stars, but it doesn't run for more than a few minutes on my rig before freezing or crashing. Once it froze when I tried to resize the main window, once when playing a slideshow, and then twice when downloading shots to iPhoto. I suspect my very unreliable wifi connection might have something to do with it, but maybe not. Anybody else seen this behaviour?
