Google Maps and jQuery Tabs

I have slight problem with Google maps included in simple jQuery Tabs.

Below I pasted the code:

jQuery:

$(document).ready(function() {

    //Default Action
    $(".tab_content").hide();
    $("ul.tabs li:first").addClass("active").show(); 
    $(".tab_content:first").show(); 

    //On Click Event
    $("ul.tabs li").click(function() {
        $("ul.tabs li").removeClass("active");
        $(this).addClass("active"); 
        $(".tab_content").hide(); 
        var activeTab = $(this).find("a").attr("href"); 
        $(activeTab).fadeIn();
        return false;
    });

});

Here is the HTML for the tabs:

<div class="bluecontainer">
    <ul class="tabs">
        <li><a href="#tab1">Tab1</a></li>
        <li><a href="#tab2">Tab2</a></li>
        <li><a href="#tab3">Tab3</a></li>
        <li><a href="#tab4">Tab4</a></li>
    </ul>
    <div class="tab_container">
        <div id="tab1" class="tab_content">
            <h2>Tab1</h2>
        </div>
        <div id="tab2" class="tab_content">
            <h2>Tab2</h2>
        </div>
        <div id="tab3" class="tab_content">
            <div>
                google Map
            </div>
        </div>
        <div id="tab4" class="tab_content">
            <h2>Tab4</h2>
        </div>
    </div>
</div>

I really don't know what to do to. Is that a general problem with google maps or there is something with my tabs? But they are working just fine with everything else.

Thank you for your help in advance

I have solved the problem.

changed hide() in jQuery to css.visibility, so the tabs looks like this.

$(document).ready(function() {

    //Default Action
    $(".tab_content").css({'visibility':'hidden'  , 'position':'absolute'});
    $("ul.tabs li:first").addClass("active").show(); 
    $(".tab_content:first").css({'visibility':'visible' , 'position':'static'}); 

    //On Click Event
    $("ul.tabs li").click(function() {
        $("ul.tabs li").removeClass("active");
        $(this).addClass("active"); 
        $(".tab_content").css({'visibility':'hidden' , 'position':'absolute'}); 
        var activeTab = $(this).find("a").attr("href"); 
        $(activeTab).css({'visibility':'visible'  , 'position':'static'});
        return false;
    });

});

Everything works just fine.
