Hi, I have 4 monitors and with Mountain Lion I could switch all 4 monitors between the host OS and any VM with a single flick of my magic mouse. Now with Mavericks I can switch any individual screen with the same mouse gesture. Although I love this feature I miss the old one too. Could I be greedy and ask that you bring back the old functionality as well please with a future version? Perhaps in the form of a hotkey I could hold whilst using the same mouse gesture? Paul.
Just figured out this is a Mavericks thing. Can be reverted back via System Preferences > Mission Control > "Displays have separate Spaces" than a reboot. Shame we cant have both but ho hum.
