When I open some applications they initially show on the monitor I last had them on, as is standard behavior, then they pop to the same coordinates on the other monitor for some reason. If I close DisplayFusion then this doesn't happen. In my DisplayFusion settings I have "Enable Window Location" turned off and I have "Move child windows to the sane monitor as the parent window" turned off.

I tried to fix this by reinstalling DisplayFusion and the behavior is the same.

I'm using a dual monitor setup with the main monitor on the right and secondary on the left. I last had these applications opened on the secondary monitor and then DisplayFusion moves them to the same coordinates but on the primary monitor where I don't want them.

I found the problem. It was "Launch Start Menu shortcuts on current monitor" it had been enabled.

Thanks anyway.
