Question

I have a bug using the jquery.mousewheel plugin where it will not recognize when I spin the wheel up. For example I try this :

jQuery(function($) {
    $('#header')
        .bind('mousewheel', function(event, delta) {
           var dir = delta > 0 ? 'Up' : 'Down';
           console.log (dir);
           return false;
        });
});

I only get Down no matter which way I spin the wheel. What could be causing this bug? Anyone else encountered this? Any ideas where I could start looking or other code I could paste in to help debug.

I am using jQuery 1.7.1

The changelog for mousewheel says “# 3.0.6 Fix issue with delta being 0 in Firefox”. Try the latest version.
