There is a problem in version 4.1 of sc.  Defined range names are not
deleted when a new data base is loaded with a G (get) command.  This
causes trouble because the range names then point at wrong (or
deleted!) cells.  Also, new ranges by the same name cannot be loaded
into the spread sheet.

Here is the fix.  Point this file at the source directory as 

patch -d <source directory> < file
