Aha, I just found this in the docs for isMovable: A non-movable window will not be moved or resized by the system in response to a display reconfiguration. (I was looking for something about this in setIsMovable, which is where I expect key information like this to be mentioned, since that's the thing developers might be calling to set the behavior.)
So, looks like I need to handle screen resizes myself, along with restoring a window on a different screen than it was saved on. I don't see any notifications that look like NSWindowScreenSizeDidChange. Where would I catch these "window is moving because the screen changed size" messages? I tried adding a NSWindowDidChangeScreenNotification handler, which *does* get called when changing a screen's size, but the notification doesn't contain the old screen size, so I can't move it appropriately. Arg. There's no accompanying NSWindowWillChangeScreenNotification in which to store the old screen size.
I'm out of ideas for something that should be really simple.
