Problem seems to be that the category-search tab doesn’t get the click event.
By the moment I patched the system doing this:
jQuery( document ).ready(function($) {
// categories
$('.categorydiv').each( function(){
var this_id = $(this).attr('id'), catAddBefore, catAddAfter, taxonomyParts, taxonomy, settingName;
taxonomyParts = this_id.split('-');
taxonomyParts.shift();
taxonomy = taxonomyParts.join('-');
settingName = taxonomy + '_tab';
if ( taxonomy == 'category' )
settingName = 'cats';
$('#' + taxonomy + '-search-tab').click( function(){
var t = $(this).attr('href');
$(this).parent().addClass('tabs').siblings('li').removeClass('tabs');
$('#' + taxonomy + '-tabs').siblings('.tabs-panel').hide();
$(t).show();
if ( '#' + taxonomy + '-all' == t )
deleteUserSetting( settingName );
else
setUserSetting( settingName, 'pop' );
return false;
});
});
})
