Is full screen in two monitors broken?

[mmichalak]

Hello All,

if I recall correctly, going full screen when having two monitors in the previous OS was not causing one of the two monitors to show that stupid texture, or go black....?

When I go full screen with Safari now on one monitor, the other monitor becomes black. Same for Aperture.

Have I missed something?
thanks

Found it

The upgrade somehow unticked the option "Displays have separate Spaces".
That cause the OS to revert to pre-Maverick behaviour when having two monitors, i.e. if you went full screen in one monitor, the other monitor was blanking out.

if you tick the option again, it reverts back to normal.
