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

Can you elaborate one what you mean by "I got alt-tab out of the game in spite of the screen still showing the game"? Do you mean the game is no longer selected? Are you running this windowed or fullscreen?

Additionally, can you submit a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

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