[jQuery] 1.3.2 broke fade and slide


Hi Guyes,
noone noted that 1.3.2 broke down fading and sliding.
Simple code like this:
    $('.showSignIn').click(function(){
        $('#passwordPanel').fadeOut(function(){
            $('#signinPanel').fadeIn();
        });
        return false;
    });
Is not working anymore. Callback fadeIn but first call do not slide
out. Same for slide up and down...
At least on FF3.
Any suggestion??
Andrea
