I'm not clear on a few things. It appears that the "panel" frame is offset one
way or the other, but I don't see the frame being set, nor the panel being
translated. You say that the order of setActivePanel…: matters, but you don't
show that the methods (odd, but not wrong, that you don't use dot notation) do
anything but change the value of an instance variable. If they actually change
view geometry, you'll have to show us.
What class does RSPanelPopoverController descend from?
What is .box? (It appears that it can be replaced only once.) Have you logged
the frames of .box, .view, and panel, before and after the replacement? And
.view.bounds?
