All was working perfect, I just Check for update and applied it from the MikTex Console and now when I work with beamer and use PS to PDF I get:
%%%% WARNING: Transparency operations ignored - need to use -dNOSAFER
and the pdf generated is not right but the ps does. I use \begin{example} \end{example}, but it does not show it correctly, look the image, in general if I use \begin{block} \end{block} appears in the same way, block with or without title.
I use:
WinEdt --> Build: 20180507 (v. 10.3) - 64-bit
MikTeX --> Version 3.14159265-2.6-1.40.21 (MiKTeX 21.1)
Gsview 6.0
Ghostscript 9.52 (2020-03-19)
What can I do to solve this? Thank you in advance.
