Horizontal drag control breaks vertical content scrolling on touch devices

Hello, 

I'd like to thank you for this plugin, I've been a huge fan of it since the first release and used it in a couple of projects! 

I used two dragdealers to implement image gallery (http://en.cafe.nov.ru/briosh) and ran into problem on touch screen devices where it breaks vertical scrolling of the page. I've just checked demo of the new version, and I'm still unable to scroll the page after I tap on dragdealer. It's a huge usability concern that would be nice to solve.
