put this in new js :

$(document).ready(function() {
$('.navbar .dropdown').hover(function() {
$(this).find('.dropdown-menu').first().stop(true, true).delay(250).slideDown();
}, function() {
$(this).find('.dropdown-menu').first().stop(true, true).delay(100).slideUp()
});
});

so simple ... no need to modify any core file
