# [pstricks] Problem with Beamer and Pstricks

I have been using Beamer and Pstricks for several years quite successfully,
and then stopped for a while (did not need any new material)  Recently I
started again, and cannot get the attached example to compile.  The LaTex
and dvi2ps seem to work, although Yap reports an error in opening the .dvi
file.  Ps2pdf produces a stack error

I have tried as many variations as I could think of.  The only way that
"things" work at all" is to remove the beamer portions and use the article
class.  There seems to be a problem between beamer and pstricks "that was
not there before"

As an aside, it seems that many of my old examples to not compile any more.
As a minimum I seem to need etex

Am using Winedt8.2  on a Windows 8.1 machine.  Have updated MikTex to the
most recent files
