Dear David, Brian and Rob, Thank you very much for your replies. Indeed, the new token works.
I never used the 'Save as default option', because I'm discouraging foolish, but perhaps also, because I seem to remember vaguely that in some grey and distant past, setting the default scale factor was only possible by manually editing the choices file. Anyhow, everything works again and better than ever before. Thanks again. Kind regards, Paul Sprangers
