Thanks for the reports. I'm not sure if this is an OSX related bug or not, but clicking Apply or changing control modes/exiting the menu will apply the saved settings changes. The toggle itself shouldn't be checked off regardless of current settings though. I'll look into that. The default fullscreen option is off, so that makes sense, even if it is a little unintuitive.
Next update has the fix for the trait selection bug. I'll look into the terminal quest. It should be unable to be interacted with when on.
