Thank you for the update Shruen.

We apologize for the delay in our response. If this is happening outside of the game itself, then we may be a bit limited in how much assistance we can give.

You can try a clean boot. Simply open the task manager and select the 'Start up' tab. Disable everything here and restart the PC. Make sure not to open any other programs or overlays. If there is another program interfering with the display or the mouse, this should prevent it from doing so.

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