I try to use BlockUI to build a web site, but I got some problem while using IE 9.

the block zone is a ifram.

the wrong display below, plz check the dialog place

on other browser, FF15.1, Chrome, IE8, it works fine.

a very simple code following, write on a onclick function with a image tag

2. $.blockUI({ message: $('#esCheck') });

here is the DIV

2. <div id="esCheck" style="display:none">
3. <p><label>LoginID:</label><input type="text" id="esCheckName" /></p>
4. <p><label>Password:</label><input type="password" id="esCheckPW" /></p>
5. <p></p>
6.         <input type="button" id="esCheckYes" value="OK" />    
7.         <input type="button" id="esCheckNo" value="Cancel" />
8.         <p></p>
9. </div>

Thank you for any help
