OK, I'll look into it.  The only thing I can think of that would cause 
this is the presence of the Matrix subroutine (which is being defined 
by Parser.pl, which PGanwermacros.pl now loads).  Parser::Matrix won't 
conflict directly with Matrix, or we would have seen that long ago, I 
think, as the Parser::Matrix package has been loaded with the Parser 
from the very beginning.
