Thank you for the reply! I have a Red Dragon M901 gaming mouse. This happens every time I use any modifier along with the current one, for example, if I use shift+1 it will attempt to use shift +1 and 1 at the same time. I'm not sure why when it is not keybinding to anything other then shift+1, As stated above the mouse works just fine on World of Warcraft and Guild wars so it is something with the Final Fantasy client. It is making my gaming mouse useless though, and I have not found another thread regarding this issue.
