I *can* read - it's just that I choose not to, sometimes. I got carried away with the possibility of being able to affect the light's characteristics... :-)

I replaced spotLite.obj with box.obj, suitably renamed - there was an rsr by the way, and a new one was created - the result is shown in the picture.

Unfortunately, the light's characteristics stayed the same. Only the preview shape was altered. As to why changing the reference line doesn't work: you did change both instances, right? It's now after midnight here, so I'll leave that question for someone else to answer.
