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

When exactly did this start happening? Did anything change/update on your PC that coincides with this?

I'm assuming you tried another mouse to see if it would have the same result?

What kind of mouse are you using? Is there a way to connect it with a wire? Does this have the same result?

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