# two psframe at same height using pstricks

I'm trying to create two psframes at same height using the following code

\documentclass[a4paper]{article}
\usepackage{pstricks}
\begin{document}
\psframe(-3,-1)(5.5,3) %frame1
\psframe(5.5,-1)(14,3) %frame2
\end{document}


given that Y coordinates are same still I can't get them at same height.

How can this be done?
