Bizarrely, that site disables not only my trackpad for scrolling, but also my cursor keys. I have to drag my pointer over to the scrollbar and move the page that way, like it's 1995.
We are working on it, will fix soon!
While you are at it, maybe make it work without javascript as well? Not everyone has it enabled for untrusted web sites, especially here.
Sorry, it's very-very complicated to get it working without javascript.
Project site has some pretty aggressive scroll hijacking, it was basically unusable on my macbook 13" under Chrome... Guys, just drop the scroll hijacking.
