Description of problem: If I log into a gnome session, the scroll wheel causes window content to move downwards if I push the wheel and upwards if I pull it. This is opposite to how it normally works pretty much everywhere. Version-Release number of selected component (if applicable): I have no idea about which component is actually responsible for this. Feel free to reassign as appropriate. But here are at least most of the possible components.

Actual results: Window content moves to the conventional direction. Expected results: Window content moves opposite to the conventional direction.
