Fixes the scroll issue on oldroid

Problem is that Android 2.x does not have a proper implementation of the overflow property. Something like overflow auto, scroll or pretty much anything is interpreted as overflow hidden (which is the worst possible interpretation). 

This might be a fix http://filamentgroup.github.io/Overthrow/

Removing that line makes the scrolling work but it might break other functionality.

P.S. I have a device running 2.2 I could help out with testing :)
