Y position not precise...?

[intersel]

perhaps change the line 921 in the iFSMAnimation.js as

 this.myUIObject.css({
                                        overflow        : 'hidden',
                                        height          : '100%',
                                        /*minHeight       : '50px',*/
                                        minHeight       : '0px',
                                        maxHeight       : heightAnim+'px',
                                        margin          : '0px auto',
                                        /*paddingBottom : '90%',*/
                                        paddingBottom : '100%',
                                        position        : 'relative',
                                        width           : '100%',

                                        maxWidth        : widthAnim+'px',
                                });
