In Parallels Desktop 12 (VM: Windows 10 full screen mode), F6 can toggle from Windows 10 to mac OS but not vice versa. When I press F6 in Mac OS, I can see only the menu bar changes to parallels desktop, but the screen focus is not redirected to windows 10. Any solution? It was working perfectly before I upgraded from v11 to v12.
When I go full screen (with the OS X little Green window control), I get logged out of Mac OS X. HUGE BUG! Anyone else? (rMBP 2014, Sierra, PD12, Ubuntu Desktop VM.)
