Thanks Magdalena, you have answered the question that I had when I first saw
GMSH months ago. I never would have guessed to pick "elementary" as the
first step in creating a new point. I have tried it and successfully created
a square 1 x 1 loop without problems. My apologies for the comment. I guess
I just needed to seriously try the tutorials, not just play with the .geo
files.
