Howdy,

The problem is with transparency. If you can use pdflatex instead of latex->dvips->ps2pdf that will work.

Alternatively, if you use TeXShop, please download the GhostsciptTransparencyEngines.zip file from my downlaod site, <https://herbs.github.io> and unzip it. If you need help isntalling the engines let me know.

Once the engines are installed place the line

% !TEX program = latexTR

at the top of the file and typeset using Typeset->Typeset (cmd-T). If you usee the latexmk based engines use

% !TEX program = latexTRmk

at the top of your file and Typeset->Typeset (Cmd-T).

Good Luck,

Herb Schulz
