[GRASSLIST:5321] r3.out.v5d error

Hi all

I'm interpolating percipitation data with s.vol.rst.
I tried to export the d3d files (elev, gradient, aspect...)
to Vis5D with r3.out.v5d and got an error.

% r3.out.v5d grid3=anasp1555_3 output=anasp1555_3.v5d
ERROR: Viz5D allows 800 rows, you have 853 rows

Now I modified the region settings so I have 800 rows.
But I still get an Error.
ERROR: Viz5D allows 800 rows, you have 800 rows (???)

Whats wrong with my grass g3d module??? I've installed
grass5.0. (compiled on my suse 8.0 Box)

Thanks for help!!
