Redirections Not Working in Internet Explorer (FF is OK)

Working on a user registration system via ZOHO accounts....

The sign-in is working, but the page redirection (OpenURL) fails for some reason. It's shared to support.

You can try the application here:
http://creator.zoho.com/niskypto/myusers/view-login/USERTYPE

htmlpage USERTYPE()
<%{
    //This script checks if the user is signed-in with his ZOHO account. If not, the page reloads.
    if (zoho.loginuser  !=  "Public")
    {
        //This script finds if the user is already in the database. If he is not, the register form appears. If he is, the personal form appears.
        if (count(DB[EMAIL == zoho.loginuserid])  ==  0)
        {
            openUrl("http://creator.zoho.com/niskypto/myusers/#Form:REG", "same window");
        }
        else
        {
            openUrl("http://creator.zoho.com/niskypto/myusers/#Form:MYPAGE", "same window");
        }
    }
    if (zoho.loginuser  ==  "Public")
    {
        openUrl("http://creator.zoho.com/niskypto/myusers/page-login/USERTYPE/", "same window");
    }
}%>
