Recently migrated to new MacBook Air M2, 2002. Previous to this (MBP 2012 OS 10) when I plugged in an external monitor, ALL open windows would show up on the external display, leaving the laptop with a clean screen unless and until I moved a window down to that screen.
Now I find that upon plugging in the second monitor, all windows remain on the laptop screen and I have to manually move them one by one to the larger screen in order to work.
Another issue: If I have (for instance) two Chrome windows open, one in each monitor and then switch from Chrome window #1 in the ext. monitor to another application (cmnd-tab), when I cmnd-tab back to Chrome it goes to window #2 rather than the previous location. As you can imagine, this plays havoc with workflow involving multiple apps.
Is there some preferences setting I need to look at to address this?
