I'm a newcomer to TeX trying to run
I cannot get it to compile correctly using pdflatex. It gives
! undefined control sequence <recently read> \c@lor@to@ps
It seems to compile alright with xelatex, though no squares are highlighted. (Expecting highlighted squares based on the ps file in the link and the error)
My setup: proTeXt, Basic MikTeX installed. Also installed pstricks and other possible related packages. Using notepad++ to run pdflatex.
