Is it just the editor which is missing the scrollbars or e.g. explorer does not have them too?
Is it happening on an arbitrary file that is longer than the window area or is it specific to a file length or a file type?

Could you try to reproduce with another Look&Feel?
Please, start NB with "--laf Metal"

Thanks,
Vladimir.

I test on PHP file. Bar vanish when code length exceed about 2000 lines of code (tested on two files, bar vanish when exceed 1957 a 2020 lines of code). I seems like bar is smaller and smaller when code length increasing and in one moment, when is size minimal it vanish.
