Long click and clicking on top menu doesn't work on secondary screen (Cintiq)

Anyone else having this issue?
While working on my Cintiq, click and hold on a tool (click hold on “contour tool” to see the “centerline editor” for example) doesn’t work. I also can’t click on any of the top menu “File”, “Edit” “View” etc.
Anytime I need to do that, I have to bring Harmony to my main display, click, then go back to the Cintiq which is super time consuming. This only started a few days ago.

Any tips on what happened or how to fix it? I already tried reinstalling harmony. Didn’t help.

Thank you!

Try rolling back your Wacom driver (uninstall/reinstall a older version).
