Title pretty much says it all. On my main PC I 3box and on my laptop I 2box. When I hold down shift and type out a msg or such the 3 on my main passes shift just fine. My laptop however does not seem to be recieving the shift key but recieves all the other key strokes. And no shift is not on the do-not-pass list

So anyways I've been trying to figure this one out but not seeing what's going wrong. Any tips would be appreciated.
