We also show that the restriction of the immersing map to a wide component is always proper. When the immersing map is injective the whole surface is a wide component. Prior to these results it was only known that injectively immersed minimal surfaces with bounded curvature were proper.Short paper, (4 pages), writen in ams-latexDifferential GeometryMetric Geometry53C42; 53C21text
