jquery 1.3.2 -- IFrame contents problem - IE8


I am using the following code to get the body of an IFrame.. it works
fine in all non IE browsers.
but not in Internet Explorer
iFrame.contents().find("body");
the debugger says: Permission denied (line 1186)(jquery-1.3.2.js)
Is there another way to get access to the body of an IFrame?
I want to add something to the iframe like this:
myElement.appendTo( iFrame.contents().find("body") );
thank you
