Spring RTS Engine

I'm using a dual screen setup. Since spring got updated to 98.0, I always need to deactivate my second screen to play properly because the cursor isn't bound to the game anymore. I tried to change some settings via spring.exe, but didn't find a solution.
I guess it's because spring is running in a borderless window mode by default now, although the option in cfg was set to 0. Changing that doesn't helped me either. Does anyone know how to fix that?

Perfect, thank you!

Actually, if you want to make it more aggressive you can do this:

so that it sends the command every 30 seconds

Untested, dunno if it works properly. More aggressive is nice because alt tabbing frequently breaks grabinput.

Freedom for Cursers- they want to have a live too you know!
