add poligons to selected dragging in "mesh editing" window

I would like to add poligons dragging a window to last selection in mesh editing mode. Actually, I can select many poligons with window selection, but can’t add more with the same selection method. I can add poligons by picking… but one by one…


What mesh editing window are you talking about?

When you enter in a mesh, you can select its parts for faces, element, material and smoothing group and flip o delete it, but if you select a group of faces selected by window, you can’t add more faces to selection by the same method. You can pick faces one by one, but not select with a new window after the first selection.
