Running a 27" iMac with a Thunderbolt 27" 2nd monitor, macOS Sierra.
When I switch between spaces with the keyboard while focused on the main monitor the focus always moves to my secondary monitor. It doesn't do that if I have Sync Grids unchecked.
However, if I click on a space with the mouse the focus will go to the monitor that I did not click on.
Any help with this would be great. Thanks
EDIT: Additionally, when I quit an app on the main monitor the focus shifts to the second monitor. But it doesn't happen the other way around.
UPDATE: I think I have narrowed it down to the way Path Finder and TotalSpaces interact. When Path Finder is not running I have none of these problems.
