[jQuery] problem unblock with IE

[jQuery] problem unblock with IE


Hello everyone .
Here is my problem : I tested this plugin in IE, and the block page
appeared..but it didn't disapear after the end of the timeout. I tried
and tried for 2 hours, but I gave up. If someone would have a glance
to my code and eventually find the error, I ll be extrememly
grateful !
$('#result-success').click(function() {
    $.blockUI({ message: '<div style="color:blue;height:50px;margin-top:
15px;" ><img src="../images/ajax-loader.gif" alt="loading" />
&nbsp;&nbsp;データが正常に更新されました。</div>' });
    setTimeout($.unblockUI, 1500);
});
This is the final problem that I want to fix for my work project.
Thank you.
