Thanks for this, but I'm still totally bewildered.  I have
located the file pstricks.pro in

    /usr/local/texlive/2021/texmf-dist/tex/latex/pstricks

But now what do I do?  Where/what is the "improved solution" that is
referred to?

Sorry for being a thicko, but I'm really out of my depth.

I thought that perhaps I should update pstricks (2021 is a bit ancient)
and to this end I downloaded the appropriate (???) zip archive from
CTAN, unzipped it and put the  results in a local directory
~/Texstuff/pstricks.

I did my best to make sure that the environment variable TEXINPUTS was
set correctly so that the new version would be the one picked up.

I then ran

   latex demo
   dvips demo
   ps2pdf -dALLOWPSTRANSPARENCY -dNOSAFER demo.ps

The same annoying warnings

appeared.

However I'm pretty sure that the new version of pstricks, from
~/Texstuff/pstricks, is NOT being used.  The screen output contained

> (/home/rolf/Texstuff/pstricks/latex/pstricks.sty ...

and

> --- We are running latex or xelatex ---
> (/home/rolf/Texstuff/pstricks/generic/pstricks.con) ...

but when I searched the output for "pstricks.pro" I found only

Can you (or anyone) give me any guidance.  I'm floundering and way out
of my depth.  Please try to express things simply, and to give complete
recipes.  Sorry for being demanding, but I really need help, expressed
in a way that can be comprehended by someone like myself, who is a bit
slow!!!

cheers,

Rolf
