The problem is that i have not one or two ... UIAnchor over the whole GUI , i have nearly every Button and Widget with his own UIAnchor script so that i have a Resolution and aspect ratio independent interface.
If i had only one UIAnchor that i wouldn't be posting here

axm0nky : I can move the panel as much as i like , because the widgets are not parented to the Pannel , but to the camera / screen.
