I compiled RC6 on Windows now, I cannot reproduce this error. Seems to
work here.

Looking at

http://trac.osgeo.org/grass/browser/grass/tags/release_20080321_grass_6_3_0RC6/gui/wxpython/gui_modules/render.py#L221

self.region directory is initialized by

self.region = self.GetRegion()

Result: on my machine RC6 works (GNU/Linux and tested on Windows too)

Can anyone confirm it?

Martin
