jquery animations happen randomly

Question

I have a kind of splash screen, where you press one of the logo's and it animates the logo to the center, then loads the content for it. Then when you press the main top logo, it hides the content and goes back to the splash screen. However I am having problems with this.

Such as, the container hides, then comes back.

Look for yourself: http://dan.roguedraco.net/SpyroDev/ If happens if you click the top logo before the content has fully appeared, but I want to allow for all these occurences. Because it is possible a user may do the same.

Javascript:

$(document).ready(function() {

var inPage = false;

$('.ajax-loader').click(function() {
    if(inPage == false) {
        inPage = true;
        var Obj = this;

        $(Obj).siblings("a").fadeOut(500,function() {
            if($(Obj).hasClass('left') || $(Obj).hasClass('right')) {
                $(Obj).animate({left:'300px'},'slow','easeOutBack',function() {             
                    $('#pageContent').fadeIn(500,function() {
                        $("#tabs").tab();
                    });
                });
            }
            else {
                $('#pageContent').fadeIn(500,function() {
                    $("#tabs").tab();
                });
            }
            $(Obj).addClass('current-project');
        });
    }
});

$('#rootLogo').click(function() {
    var Obj = $('.current-project');
    if(inPage == true) {
        inPage = false;
        $('#pageContent').fadeOut(500,function() {
            $(this).hide();
            if($(Obj).hasClass('left')) {
                $(Obj).animate({left:'0px'},'slow','easeOutBack',function() {
                    $(Obj).siblings("a").fadeIn(500);
                });
            }
            else if($(Obj).hasClass('right')) {
                $(Obj).animate({left: '600px'},'slow','easeOutBack',function() {
                    $(Obj).siblings("a").fadeIn(500);
                });
            }
            else {
                $(Obj).siblings("a").fadeIn(500);
            }
            $(Obj).removeClass('current-project');
        });
    }
});

});

.stop()

have you tried to use .stop() before your .animate() and .fadeIn() and other animate methods? like: $(Obj).stop().animate({left:
