Document Classes ⇒ PSTricks Bug: \ncline cannot connect "tr" node to "Br" node.

[fractal.generator]

Dear all,

I want to connect "top right" (of a box) node and "Base right" node using the following code:

Code: Select all

\documentclass{book}
\usepackage{pst-node,xcolor,graphicx}
\pagestyle{empty}
\begin{document}
\psset{linewidth=0.01pt}
\scalebox{20}{%
	\rnode[tl]{tl}{%
		\rnode[Bl]{Bl}{%
			\rnode[tr]{tr}{%
				\rnode[Br]{Br}{%
					\psframebox[framesep=0]{\color{cyan}\TeX}}}}}
\SpecialCoor
\psset{dotscale=0.1,linecolor=red}
\psdot(tl)\uput{0.5pt}[135](tl){\scalebox{0.1}{tl}}
\psdot(Bl)\uput{0.5pt}[180](Bl){\scalebox{0.1}{Bl}}
\psdot(tr)\uput{0.5pt}[45](tr){\scalebox{0.1}{tr}}
\psdot(Br)\uput{0.5pt}[0](Br){\scalebox{0.1}{Br}}
\psset{nodesep=0,arrows=<->,arrowscale=0.2,linecolor=blue,linewidth=0.05pt}
\ncline{tl}{Bl}
\ncline{tr}{Br}
}
\end{document}

Unfortunately, the output is a bit strange as follows:



The strange case is that the command

Code: Select all

\ncline{tr}{Br}

did not draw a line connecting tr and Br.

other information:

1. there is no problem for \ncline connecting "top left" and "Base left".
2. there is no problem for \ncarc connecting any two nodes.


Any suggestion for me?

Thank you in advance.
