Thanks for your quick response.

I use a laptop with external monitor but I dont expand the laptop screen and use the external monitor as the only screen.

Is there a option to show which window is allocated to which screen?

Console: The new T1
Software: Titan Go 12.1.8.5

When I try to open the trigger window it never open in the current show.
In a new show I can open it as expected.

Is there a option to deactivate it or is it a bug?
