OS X 10.1.5 seems to have broken or changes a number of graphics/attributes functions in VW, among them the eyedropper tool and the gray visibility in classes and layers. The eyedropper tool either fails to change the color of a line, etc., or makes it white and therefore invisible (using a white background). What used to be gray visibility has now become blue or magneta. The gray visibility appears "normal" when viewed in Black/White Only (in Preferences). Please help!!!
