I've switched to Mavericks and i wonder if the behaviour i'm seeing is a bug or a "feature".
It used to be that whenever you created spaces you could assign apps to a specific space, say Mail.app to space #2. In 10.8 that functionality was lost, but apps seem to 'remember' the space they were closed in. So if i opened Mail.app, dragged it to space #2, switched back to space #1 and open Mail.app again it would still open in space #2.
Unfortunately this seems to be broken in Mavericks. If i try the same thing the app simply opens in the space where i'm currently in, so i need to drag the app to the correct space again. Very frustrating.
Does anyone know a solution to this problem or should i try to file it as a bug with Apple?
