Hello.
Sometimes ago, when I opened an application with the taskbar on my second monitor, the application windows opened in the second monitor. But actually it doesn't work anymore. It was very useful.
I don't know exactly when it started to not work anymore. So I don't know if it is a bug or if the functionality doesn't exist anymore. In the settings, in the "Window Management" tab, it doesn't matter if I check it or not, nothing change. The only way to make it work, it's to uncheck "Only move windows opened from the Start Menu (only with Windows 7 or Classic Shell)", but it is not the way I like it. Actually, I am on Windows 10 with Open-Shell.
I am using the 10.1 beta 3 of Display Fusion.

Hello, thanks for the answer.
For me, this setting doesn't work, even with the first window created.
With this trigger, every new window open in the monitor where the mouse is, but I would like only the window opened by the start menu do this.

I'm facing the same issue as well. Even when I enable and configure the trigger a child window doesn't move to the active monitor.
For example:
When I open Outlook it starts on the active display, but a new email window opens on the other display. It was working before, but now its not anymore.

When I roll back to v9.9, it works fine.
