What I mean is that a window selection shouldn't be allowed to select individual attributes of a component without selecting the entire component. In 1.8.2, you have to be extremely careful with window selections to avoid accidental selection of single attributes (refdes, value, etc.) of a component. In 1.6.2, a window selection can't select a single attribute: if the window doesn't completely enclose the component, none of the component attributes are selected.
