New Post: IE11 ckeditor.js Access is denied Issue

When using IE11 and a user clicks on the Link option on the toolbar,
The Dialog shows up, but the buttons do not work.

In debug mode, I can see "Access is denied" in ckeditor.js on the following line:

getFrameDocument:function(){var a=this.$;try{a.contentWindow.document}catch(b){a.src=a.src}
    return a&&new CKEDITOR.dom.document(a.contentWindow.document)
}

Also: the dialog isn't hiding any of the non-selected "Link Type" sections.
So, the link info tab has the UI for all of them showing ,URL, Email, Portal Page and Email Address.
(likely because of the JS issue above.)

Any ideas?
