Microsoft problem with publishing

[bobo.cx]

I hope this is the corect forum to post this question

when ever I try to publish an article I copy it from microsoft word and post it in the browser it shows this "<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" />"
This happends to all my articles. I can not see this gibberish until my article goes to the browser.

Please help me with this
