I'd simply forgotton this not so unimportant fact ...

Yes ! Now it begins to work. I also increased the intervals in the test
scene. In the original scene the beams looked a bit like a string of beads.
Increasing the intervals from 10 to 30 helped to produce a more constant
beam. But this also demands a greater rendering time.

Originally I wanted that a spot should shine out of every window. As I made
7x49 windows in total I think I'm going to drop this idea ...

You helped me a lot, especially in encouraging me to read more in the help
files   :)

Thanks,
Bu.
