Re: Sims camera controls are messed up after Windows Update
@kikinizzy Please disable any overlays you have running while you play: Steam, Discord, etc. Please also disable Origin in-game. Hover over your username, select Application Settings, then the Origin in-game header, and disable the option at the top.
If that doesn't help, please test in fullscreen, windowed fullscreen, and windowed modes, and let me know whether the middle mouse button function works normally in any of them.
