I don't know when the next build is expected (and maybe the last one before sending this version to DVD burning), but I just hope they will not leave Spaces in this state
This is the last thing annoying for me : Switching between spaces with the keyboard when you have windows opened is no more fluid as it can be with leopard, and when you have Application assigned in specific Spaces opened
you need to click twice on their icon in the dock to make them come to foreground
Or I am the only one with this problem, and a clean 10A421a will resolve this
