Sounds to me like the footer and detail controls are part of the same group. When you select one of the footer controls, does a small "ghosted" box with a cross inside it appear anywhere? Look real carefully as it can be hard to see among a whole lot of other controls. If so, then you have a grouping and trying to move one is affecting the whole group. The solution would be to select one, right click on it and go to Layout> and select "Remove". It doesn't remove the contol, just the grouping.
The more we hear silence, the more we begin to think about our value in this universe.
