It's easier to explain if I show you my my desktop config:

1 and 2 are my main monitors. "Monitor 4" is an output to a TV in another room. I usually have Desktop Preview anchored (with auto-hide) to the right side of Monitor 2.
Since a recent update, Desktop Preview no longer will anchor to the right side of Monitor 2: it either anchors to the Top/Bottom of Monitor 2 depending on where I initially put Desktop Preview box.
If I move Monitor 4 so it's no longer the most rightward screen, the Preview works like it used to, and anchors/autohides fine. Is this intentional? Is there any chance of reverting the behavior?
