jQuery modal window closes incorrectly in Internet Explorer

Question

I'm having some problems regarding a jQuery modal window. I'm a dba and SQL programmer and my goal is to build up a query which dynamically builds an HTML which contains a flash which links to a modal window that has another flash in it. Well the query is done and works flawlessly. However, I tried it on Internet Explorer and (unlike firefox and chrome) when you want to close the modal window it closes the whole browser window (with a warning message that says "beware, the browser's trying to close this tab etc").

I used an already existing jquery modal window code and styling (I believe that both matter). The problem is, that the whole query is done and if I change the whole jquery modal window, I'll have to change the query's logic, and drastically (believe me, I've checked).

So, my fastest solution would be to correct the jQuery code that is messing up the whole close thing (changing the sql stored proc would take a LOT of work). This is because the original example I used as a reference had this problem (I just didn't notice, due to jQuery supposively being a cross-browser solution for everything). You will see that it works flawlessly on FF and Chrome but not in IE Here's the link: http://www.mediafire.com/?mcz70n870qmjch9

Thanks a lot!!!

Just in case I'm posting the code here as well:

    padding: 0;
    background: #131313;
    opacity: .85;
    filter: alpha(opacity=85);
    z-index: 101;
}
.modal-window {
    position: fixed;
    top: 50%;
    left: 50%;
    margin: 0;
    padding: 0;
    z-index: 102;
    background: #fff;
    border: solid 8px #000;
    -moz-border-radius: 8px;
    -webkit-border-radius: 8px;
}
.close-window {
    position: absolute;
    width: 47px;
    height: 47px;
    right: -23px;
    top: -23px;
    background: transparent url(../images/close-button.png) no-repeat scroll right top;
    text-indent: -99999px;
    overflow: hidden;
    cursor: pointer;
}

Thanks a ton in advance everyone =-)

EDIT : Daniele suggested that the problem might be on this line:

jQuery('.' + options.modalClassName + ', .' + options.overlayClassName).fadeOut(_settings.fadeOutSpeed, function () { jQuery(this).unbind().remove(); });

I did what he suggested and the result was this: It still doesn't work at all on IE (meaning that it still asks to close the whole window and not just the modal), and correctly shows and closes a first modal in FF and chrome, but after closing the first one its not able to correctly show another one.

Answer 1

Replace close() method of modal with closeModal or something similar:

$.modal.closeModal = function () {
    _modal.closeModal();
}

[...]

this.closeModal = function () {
        jQuery('.' + options.modalClassName + ', .' + options.overlayClassName).fadeOut(_settings.fadeOutSpeed, function () { jQuery(this).unbind().remove(); });
    }

[...]

$close.click(function () { jQuery.modal().closeModal(); });
            $overlay.click(function () { jQuery.modal().closeModal(); });

for me it works...
