Office button flashes continuously ... How do I stop it?

I have just installed Office 2007 and am using Word. The Office
button in the top left flashes continuously - maybe pulse would be a
better word, from the normal blue background to an orange
background. I can't find out what this is telling me or why it is
doing it, but it's driving me nuts. How do I sort it out?

Microsoft Office issues:
microsoft.public.office.misc

Have you tried repairing your installation?
