I have enable the option "Display expanded", so now I can show by default the first 8 lines of a code, but impossible to scroll down (no scroll bar), and if I expand the box, when I collapse it, I again a box on one line (not too severe, but disconcerting).
If it's too complicated too made what I wish, do you know how I can keep the original behavior of Prosilver theme (a codebox with scroll bar but with colored code)?
