PDFs don't play nice with SmartScrollX
 

SmartScrollX is useful application that provides smooth scrolling inside OS X. It appears however that if I have it enabled, I can't use my trackpad to scroll PDFs. Not a huge deal since I can still use the scrollbar or disable smartscrollx while browsing PDFs from inside OmniWeb, but I thought I'd bring it to the developers' attention since it does detract from the overall great experience of the browser :)
