Yes, this is the file I was talking about. If editing it doesn't help, I don't have a freakin' idea what is going on. It seems that on your system, something overrides those values no matter what, and AFAIK you've checked everything that could do it, humanly possible. I really would like to help you (I'm following your issue since start), but nothing more than xkcd's "your computer is literally haunted" comes to my mind at this point
