Issues with Parallels 12 and Fusion 8.5 FullScreen with Sierra GM

[MrGimper]

Is anyone else running Parallels 12 or Fusion 8.5 with dual monitors, and finding that a VM running full screen with the "use all monitors in full screen" doesn't actually use both monitors?

I *think* it's Sierras "put multiple windows in tabs by default" that is causing the issue as I can see a corrupted tab bar at the top of the that's working screen.

Anyone know how to stop the new "put all windows in tabs" default behaviour ?

Cheers

System Preferences -> Dock -> Prefer tabs when opening documents.

Awesome, thanks... couldn't see it for looking. Setting to "Manually" resolved the issues.
