How do I stop my iMac screen from moving to the side permanently?

I hate when I have taps open and I am using one tab and while using it the whole screen disappears to the side. How do I stop the screen from moving to the side permanetly?

There's another feature that you may want to turn off. I ran into it when upgrading from Ventura to Sequoia – so I don't know if it is in Sonoma.


This is in System Settings > Desktop & Dock. t's called "Drag windows to menu bar to fill screen." If you're used to having a lot of nearly full-screen windows, and moving them around from time to time, it is easy to accidentally bump the menu bar, at which point this "feature" destroys your screen arrangement.
