Only in the newest version does the problem extend to Windows Explorer as well. The problem has existed in Word through several iterations of Office. Anyway, I already did all of the things you suggest, along with any other suggestion I’ve found on-line.
Irony doesn’t translate well to e-communication. I didn’t think you or anyone else had any influence on Microsoft. If the repair doesn’t work have you tried uninstalling and reinstalling Office? Have you tried repairing your Office installation?
What steps have you taken to resolve this? We have no influence with Microsoft and Woody has effectively severed his ties with this site.
