Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

To clarify, the issue is that your character moves slightly when they are not supposed to correct? Or is it that it isn't moving in the way you want them to move?

Have you been able to replicate this with any other device (such as another controller or a traditional keyboard)?

I'm assuming that this gameboard has it's now set of drivers, have you tried reinstalling them?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
