iPhoto, for example, takes about 30secs to open. If I'm using Safari and decide I want to upload a photo, opening iPhoto and then going back to Safari simply means that iPhoto will jump to the front with it's big, blank screen and spinning beachball five or six times. It's like fighting with my Mac. It's like I'm constantly clicking back to Safari and then a few seconds later my Mac will pop it to the front as if to say "You wanted iPhoto, so here's iPhoto - watch it open." It's very annoying. Can I set something to allow applications to load in the background?
