opening photos on my external monitor window
I just updated my photoshop cc 2018. I keep my tools and photoshop window on my laptop and open photos on my external monitor. Then I usually hit command O to make it full screen. Up til now, it always fills the screen on the monitor ... now for some reason when I hit those buttons, it switches to the laptop screen and is inside the photoshop window .... this is cumbersome and time-consuming and I've looked at every option and can't figure out how to get it to open on the big screen.
