Has anyone else noticed the new Spaces behaviour in 10.5.3? From http://daringfireball.net/2008/05/spaces: *Emphasis mine. This must be a godsend for those who really wants Spaces to be task-oriented rather than app-oriented! Simply put, there is a lot less being automatically swooshed around now. It is easier to open a new window of an app in the current Space, without having to drag a window from another Space. Too bad this still does not address auto-swooshing when apps call for attention. You are still swooshed to the Space where the app is calling for attention. (Thunderbird, I'm looking at you! ) Still, I love this new Spaces improvement! It is miles better than relying on the "no autoswoosh" hack! Gotta love Apple for listening to feedback and making improvements!
