The scrolling seems to be the default one,it just moves less than it used to. (aka: need more ticks)
The design of the site pretends a smooth and reliable scrolling, if the mentioned solution is indeed the one meant to be then i'd change the first part of the website (the scroll to continue plus the button).
For some reason, the text is now fuzzier than before unless i zoom 175% or more (using a 1400x900 resolution).
Otherwise i believe it's all right.
