[GRASS-user] NVIZ vectors

I used d.nviz to create a sample script that I am using as a basis to create a script for NVIZ. The problem is that I am not seeing any sites showing up. I tried using the -e option and I see that it adds:
SendScriptLine "Nshow_vect on"
SendScriptLine "Nshow_sites on"
to the script. By adding these two lines I am seeing the addition of my vectors, like I want, but not my sites. If I manually move around in NVIZ the sites are showing up fine, but then when I run the script, to save snapshots, the points sites don't show up.
I am using the mac binary of 6.3.
Any idea why, or what I can do to get them to show up?

Thanks,
