Can't move spaces from one screen to another I am using OS X 10.9. I am unable to drag Desktops from one screen to another, I am only able to switch arrangements on the screen that its on.

Here are my Mission Control settings

EDIT: Very strange, after a reboot the functionality seems to be working now without me making any changes.
You can only move non-active desktops between screens.

If the desktop you want to move is the only desktop on the screen, then create another desktop, make that the active desktop, and then drag the non-active desktop.
