Well, I found the problem. I work on the road alot, so I bought a gaming notebook. I can type [,], and \ all I want out of the mod but in MWLL my '[' key won't type. My ']' key will type [ in game and the '\' key thinks it is a ]. The keymapping was off. I went into the keyboard and mouse menu and changed the Crysis/MWLL fire mode and when I pressed \ a ] showed up. So now, in game, when I type the \ it thinks it is a ] and chain fire works as published. Is this a computer/notebook specific problem or a bug? Guess I'll report it as one and see what happens. Should be interesting when I try to map my CH HOTAS when I get home this week, wish me luck!
