When I was watching WWDC '07 Kenote I found that Expose is an app in new release of Mac OS X. It is visible when SJ is showing Stacks in slow motion. I don't know what kind of process was it earlier (System Events run it???) but I'm quite sure it wasn't an app. Launching Expose has few results so it can not launch one process. It can not launch all of them either. It has no sense for me. What do you think about it?
