Tip: Send your USCICON to lower left corner.

Daily Autocad: "If you are sick and tired of the Ucsicon that moves around with you and follows you, solution is pretty simple. When we open a new AutoCAD drawing, Ucsicon becomes available and will be locked over the origin. However, if the origin remains in the middle of our drawing, Ucsicon will disturb us as it will always be in the view."
