[jQuery] Not working in IE

[StirolXXX]

Hi! I have a small but pain-in-the-ass problem.

Here is my code:

var ExternalLinks_InNewWindow = '1';

function initSpoilers(context)
{
        var context = context || 'body';
        $('div.spoiler-head', $(context)).click(function(){
                var code = 
$(this).next('div.spoiler-body').find('textarea').text();
                if(code) $(this).next('div.spoiler-body').html(code);

                $(this).find('div.spoiler-head').toggleClass('unfolded');
                $(this).next('div.spoiler-body').slideToggle('fast');
        });
}

function initExternalLinks(context)
{
        var context = context || 'body';
        if (ExternalLinks_InNewWindow) {
                $("a.postLink:not([EMAIL PROTECTED]'"+ window.location.hostname 
+"/'])", $
(context))
                        .bind("click", function(){ return 
!window.open(this.href); })
                ;
        }
}

$(document).ready(function(){
        initSpoilers('body');
        initExternalLinks();
});

The problem is that this code working PERFECTLY in firefox but not in
IE: on reload of page spoiler aren't acting at all.
On load page via link the spoilers are working fine :(

What could be wrong?
