Thank you Inger - your answers and tips will help me a lot to go on. For me such answers are pure energy. They should be written in a help guide for "problems while making and using Components".
Did you make a new Nav for me ? Your mail has no link to it or zip attached. You may send it to my email adress as well at ergo@snafu.de.
In case you come to Berlin to inspect your "Berlin luggage" I'd be happy if you contact me for a beer or a coffeecup.

Last time I was in Berlin was 2 years ago. It looks as if it will be some time before anyone can travel safely to any place now. But I would love to go again.
