Paper size default, pstricks

[Kostas Oikonomou <oikonomou att com>]

Hello,

I'm just beginning to use Dia, and I have a couple of questions:

1. Is it possible to set paper size as a global default, e.g. in the
~/.dia/diarc file?

2. Vertical centering of text inside a box doesn't seem to work with PSTricks,
i.e. when I export a .tex file.  I group the box and the text, and select Center
in Alignment.  Is this a bug, or am I doing something wrong?

Thanks very much.
