I recently upgraded to Microsoft Office for Mac 2008. After turning off the WYSIWYG font menus (due to the exasperatingly long startup time for Word), changing the default file format back to .doc from .docx, etc., things began to work for me.
I’d always been frustrated with the Paste Special approach to pasting in unstyled text from the clipboard – but had just lived with it in prior versions of Word. Joe Kissell’s spent a couple of hours writing a script that solves this problem in Word 2008. Highly recommended!
