Problem with preventdefault on mousedown event in Internet Explorer 8

[frgformenton@…]

This demo locks the scroll when the user clicks with the mouse wheel button ​http://jsbin.com/agoyum/edit#source but this does not work in IE8 The preventDefault just does not work.

This example is the same thing, but does not use jQuery, and works perfectly in IE8 ​http://jsbin.com/isefek/edit#source Note that the PreventDafault works correctly.

This is a bug in the implementation of the method 'on' from jquery?

jQuery doesn't normalize event.button, look at event.which instead or take your chances with event.originalEvent properties.
