Yes, I see the same as you---all of the time, but that exactly is what's puzzling me:
Within the questions' preview the scales/sliders have the proper size,
...but then, if they are integrated in the questionary's pages (via %input:questID%, as you suggest here:
https://www.soscisurvey.de/help/doku.php/de:create:inputs-single) they now, in the new SoSci version, get scaled up to the maximum available width (and in a previous SoScie version they had the same size as in the preview... and I don't find methods to restore that state until now using the new version).
Please, have a look at page 46 of "markenSprech3" which I have especially built for you, in order to clearly demonstrate the problem.
(The pages 8 to 43 are those, where the scales in previous versions were the size that is showed in the preview.)
Thank you again!
