Well I'm probably too silly to understand that. I see two basic cases when trying to calculate the height of windows in change_frame_size: (1) If toolbar and menubar height are not included in the total height of the frame, then the root window and the minibuffer window constitute the total height of the frame. (2) If toolbar and/or menubar are included in the total height of the frame, we have two possibilites: - The height of any such bar is indicated in lines. In this case we subtract their heights as multiples of canonical line heights. - The height of such a bar cannot be calculated in canonical line heights. In this case we must have subtracted their height from the total frame height and rounded the remainder in terms of canonical line heights _before_ calling change_frame_size so we have case (1) again. In any case the value for the frame root window/minibuffer window heights is specified by subtracting #define FRAME_TOP_MARGIN(F) \ (FRAME_MENU_BAR_LINES (F) + FRAME_TOOL_BAR_LINES (F)) from the line numbers value passed to change_frame_size. At the time we do that, the lines of the bar must either not have been reflected in the argument for change_frame_size or be specified as numbers of lines. martin
