This one is an old chestnut. There are two functions in the HTML editor which attempt to strip out the Word specific HTML: if you paste the Word text into the HTML editor window with CTRL-V or you can use the "Clean Word HTML" button in the top row toolbar.
However, it usually still leaves a lot of rubbish in there. I think using the HTML Tidy program is the best way to clean it up.
It is a real headache working with MS Word text in the HTML Editor. Sometimes it is easier just to upload it as a webpage resource (make it open in a bottom frame) or just bypass the Word altogether.
Other might have other suggestions,
HTH,
Tim.
