--- Comment #499 from Sven Arvidsson sa@whiz.se 2011-05-14 08:24:13 CDT --- STALKER: Clear Sky is also improved with git master. You still need to start the game with "-i" to get any mouse movement at all, but now there's no need to toggle this option on and off the get mouse movement in the inventory screen.
