That's good to know. I thought it was just me.

Grrreat. I think that's what I did. I think.

Check.

Okay, I didn't notice this! I have the newest version of RISA-3D, and I have noticed the documentation seems a bit "behind the times." If you hadn't pointed this out I would never have figured it out myself!
Thanks!
More later, I'm sure. Hope this is helpful to others listening in.
