Having used an early seed of Leopard on a developer friend's machine, both he and I were a little puzzled about particular window behavior we encountered whilst using Spaces - and I just wondered whether anyone here has any feedback or opinions on it. Basically, we set up a few different spaces and then opened various apps and a few Finder windows. After having distributed these windows around the different spaces, we noticed that something quite irritating (at least to us) happened when closing a window belonging to an app that still had another window open in a separate space: the space would switch away from the one you're currently working in, to the one which contained the remaining open window. You can try this yourself; just activate Spaces and then open two Finder windows. Move one of these windows into a separate space and then close it - you should then see the workspace jump back to the one with the remaining open Finder window. Both I and my friend found this behavior puzzling (and, quite frankly, unintuitive), because often we'd close a window - not remembering that there was another window belonging to that app open elsewhere - and then be suddenly and unexpectedly transported to another space with the remaining open window. Of course, we then had to manually navigate back to the space we were originally in in order to continue working. Obviously, this behaviour is an extension of OS X's default window behavior which brings all the windows belonging to an app to the top level as each previous one is closed. However, in Spaces, I'm just not sure that such behavior is appropriate. So what do you think? Is this the correct way Spaces should function, or is it a bug which hampers productivity?
