Specific Apllication On Specific Screen

[BomBas]

Hi, I own a MBP and I connected an external screen to it. Now, I do almost all my work on the external screen, but I want a specific application to always open on the screen of the MBP itself. Now, it works fine until I enter "full screen" on that specific application, then the application shows on the external screen. How can I make the application to be ALWAYS on the MBP screen?

Thank you very much!

When I go full-screen, it always shows up on the MBP screen and makes the external screen useless - opposite of your operation. Maybe it's the arrangement? I have the MBP screen arranged to the left of the external.

It might be, I have the MBP right to the external screen. But I think it just opens on the main screen, the one with the dock the upper-bar.
