# Missing text from boxes in block diagram (pst-sigsys/pstricks)

I am trying to make a block diagram using pst-sigsys/pstricks. The text however isn't in the boxes but is stashed on the left. I absolutely run out of ideas what might be causing it to happen. Any pointers will be greatly appreciated. Thank you!

Minimum example:

\documentclass{article}
\usepackage{pst-sigsys}

\pagestyle{empty}

\begin{document}

\begin{figure}[ht]
\centering %
\begin{pspicture}[showgrid=false](0,5)(8,9)

%--- Define blocks ---
\psfblock[framesize=2.5 1](2,7){R11}{Axon Count}
\psfblock[framesize=2.5 1](6,7){R12}{Axon Diameter}

%--- Connect blocks ---
\psset{style=Arrow}
\ncline{R11}{R12} \naput[npos=.5]{(+)}

\end{pspicture}
\end{figure}

\end{document}

Welcome to TeX.SX. I get the text properly boxed; it may be a problem in the viewer. Did you try producing a PDF? – egreg Jun 19 '11 at 8:22
Do not view the DVI output. Always look at the PS or PDF output (as already mentioned). – Thorsten Donig Jun 19 '11 at 8:32
Thank you egreg. Indeed if I produce DVI and convert it to postscript everything looks okay, but if I do DVI -> PDF things are out of whack. I guess there is a reason this package is called pstricks ;-) Thank you once again! – Jacek Jun 19 '11 at 8:38
@T.D: Thank you! – Jacek Jun 19 '11 at 8:39
I suggest somebody turns his comment into an answer. Btw. I can confirm it works with XeLaTeX too. – Stefan Kottwitz Jun 19 '11 at 12:04
