On Windows 10, the focus stealing does not happen with InDesign CC 2018. Same with Illustrator CC 2018.
However, as some users have noted, focus stealing happens with Photoshop CC 2018.
We’d like to know if you are still experiencing this issue with InDesign.

Not the worst problem I have in my life right.
Am I being punished for not using a Mac?
