A user I support is experiencing sporadic light blue and dark blue
highlighing in table cells when he types. It is not due to table style or
cell shading. He has a plain (white background with black text) cell
selected, and when he starts typing the row is highlighted in blue -
sometimes a light shade and sometimes a dark shade. It makes the text very
difficult to see at times. Happens spordically. When he clicks out of the
cell to finish his editing the highlighting disappears.
