When you say ps -x's output I'm assuming you mean the arguments on steam.exe? I've included the relevant lines to show you what I mean. Code: 3440 ? Sl 0:00 C:\windows\system32\services.exe 3442 ? Sl 0:00 C:\windows\system32\winedevice.exe MountMgr 3449 ? Sl 0:00 C:\windows\system32\plugplay.exe 3454 ? Ss 0:00 C:\windows\system32\explorer.exe /desktop 3455 ? Sl 0:20 C:\Program Files\Steam\Steam.exe 3601 ? Rl 0:46 c:\program files\steam\steamapps\common\dead space 2\ 3614 ? Sl 0:00 C:\Program Files\Steam\GameOverlayUI.exe -pid 82 -man Dead Space 2 doesn't even show an exe, and the path is in all lower case (though it doesn't matter on windows, I know).
