Dialog box ignores input meant for other controls

Enter/Space do not advance the dialog while a text field has focus, and a
click over another control that stops the mouse (a tool panel drawn over the
dialog area) belongs to that control. DialogBox reads input in _Input, before
the GUI, so both used to advance the dialog as well.
