Yea I have one of these mouses, actually bought it slightly before 2.3 came and worked fine but after the patch the key binds no longer worked and only does the standard 1 through =. I also remember a few threads about this issue popping up around that time and there was never any response. They either broke something and don't care or the purposely made it not work. Idk but it would be nice to be able to use the mouse like ti suppose to be able to again.
