Using Chrome this website does not scroll (circa 1995) unless scrollbar manually clicked. Glancing at the site JS sources I believe it is probably due to the fancy smooth-scroll jquery functions. Either way, it really has been since about 1995 that just being able to scroll a website up and down to read it was in any way optional. 🙂
Note I did run with zero extensions, etc. and incognito and it is definitely something incompatible in the site's code conflicting with Chrome.
