[pstricks] pst-3dplot

[Pedro Jorge Caridade]

Happy new year to everyone in the pstricks list, and all the best in 2008!
I'm using pst-3dplot to make some schematic representation of a 
molecular cluster. My problem is that the pstThreeDPut is giving some 
strange (very strange!) result. Consider the minimal example:
\listfiles
\documentclass{article}
\usepackage{pstricks}
\usepackage{pst-3dplot}
\pagestyle{empty}
\begin{document}
\begin{pspicture}(-0.5\textwidth,-0.5\textheight)(0.5\textwidth,0.5\textheight)
\pstThreeDCoor[xMin=-2,yMin=-2,zMin=-2,xMax=2,yMax=2,zMax=2,IIIDticks]
\pstThreeDPut(1.5,0.0,0.0){1}
\pstThreeDPut(1.5,1.5,1.5){2}
\end{pspicture}
\end{document}

The label "1" is in the proper position, while "2" in my humble opinion 
is not. It should be 1.5 in x, 1.5 in y and 1.5 in z. Of course it can 
be due to the matrix rotation, but is strange to me, and looses 
completely the sense of the 3D perspective. Is the behavior ok?
I'm running a TexLive 2007 and the list file is:
