Whenever I open the Total War launcher from steam my mouse begins immediately dragging across my entire desktop. It is only when I have the Launcher or Wh3 running and "active". if I tab out and click on any other application or my desktop the dragging stops. I have tried 2 separate mice, switching Usbs, swapping some graphics setting around and restarting my whole system. Was playing earlier today and everything was working fine, but now the game/ launcher is actually unplayable. Any ideas for a fix?
