Sesui APP gets stuck OFF screen
What this means is that when you launch the application if comes onto the task bar but it is not visible.
You can see my Sesui has been launched however i am unable to see it if I click on it, you generally see a very quick flicker of Sesui coming from the edge of the monitor but it doesn't actually appear.
What you need to do is Hold down the Shift key, then right-click on the Sesui application icon in the Windows taskbar. On the resulting pop-up, select the Move option.
Press the arrow keys on your keyboard to move the invisible window from off-screen to on-screen.
