Well, that's certainly quite bizarre. I wish I could think of something else
but I'm stumped. I've never experienced that problem on my system, and I don't
know why yours isn't allowing the write. Is it possible there was some error in
copying the script? It seems unlikely but that's all I can come up with at this
point. If you have somewhere I can send my actual script and service files I'd
be happy to send them to you. Otherwise I'm just out of ideas.
