onComplete: addClass problems!!!

[aka CoolWhiteDude (aka c1hundred)]

Hi, I'm new to this group...

I have the code below which removes and adds a class onComplete of a
morph effect, this works fine but only after the second this morph is
used. I mean load the page activate it once and it doesn't work, any
other time after and it does, can anyone tell me why? All replies are
kindly appreciated.

$('openLightbox').addEvent('click', function(e) {
    e.stop();
    // Changes the element's style to .myClass defined in the CSS
    anotherEl.fade('0','1');

    var LightboxOpen = new Fx.Morph(anotherEl,{
            onComplete: function(){
                $$('.content').removeClass('contentHide');
                $$('.contentHide').addClass('content');
            }
    });
    LightboxOpen.start('.LightboxOpenClass');
});
