Paste from Word, multiple nested span

Hello,

Have an issue with CKEditor 4.1.1 and pasting from Word.

I have configured CKEditor as such:

CKEDITOR.config.pasteFromWordPromptCleanup = false;
CKEDITOR.config.pasteFromWordRemoveStyles = false;
CKEDITOR.config.pasteFromWordRemoveFontStyles = false;

Even pasting a very simple test of one word, red, bold, find size 20 (see attached Word document) produces multiple nested span tags:

<p><strong><span style="font-size:20pt"><span style="font-family:arial,sans-serif"><span style="color:red">HELLO</span></span></span></strong></p> 

I've tested in Firefox, IE9/8/7 and Chrome with the same results.

Is there an option to fix/disable this, or any code I can use to fix this?

Thanks,
Mike
