Reveal Modal not working on IE (no animation in the code)

Question

I'm working on a website which uses reveal modal to open divs. I'm using the non-jquery version and I get the modals to open on both Firefox and Google Chrome, however, they don't seem to appear on IE. I read on the forum that there is an issue with IE and modal animation but I haven't included them in my code. Can anyone help me figure out the problem? I am using the latest versions of all browsers.

Code

    <ul>
        <li><a href="#" data-reveal-id="myModal1">REGISTER</a></li>  
        <li><a href="#" data-reveal-id="myModal2">ABOUT US</a></li>
        <li><a href="#" data-reveal-id="myModal3">IMPROVE</a></li>            
        <li><a href="#" data-reveal-id="myModal4">CONTACT</a></li>     
    </ul> 

    <div id="myModal1" class="reveal-modal"> 
        <p style="margin-right:10px; margin-left:10px">
        Text
        </p>
    <a class="close-reveal-modal">&#215;</a>
    </div>

    <div id="myModal2" class="reveal-modal"> 
        <p style="margin-right:10px; margin-left:10px">
        Text
        </p>
    <a class="close-reveal-modal">&#215;</a>
    </div>

    <div id="myModal3" class="reveal-modal"> 
        <p style="margin-right:10px; margin-left:10px">
        Text
        </p>
    <a class="close-reveal-modal">&#215;</a>
    </div>

    <div id="myModal4" class="reveal-modal"> 
        <p style="margin-right:10px; margin-left:10px">
        Text
        </p>      
    <a class="close-reveal-modal">&#215;</a>
    </div>             

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"></script>
    <script src="jquery.reveal.js"></script>

Answer 1

Ok, I figured out what the problem was. It seems that the reveal modal was conflicting with the gooogle maps geolocator. Just realized that I forgot to set googleapis sensor to true. As soon as I changed it to on, the modals work on IE. Not sure what the link is between the two but it's good to see that it now works.
