If not, download the file from the link below and then run it to install SP1. (Yep, it's a large file so you'll need broadband or a friend that has broadband.) After installing the service pack, then visit the Office Updates site and install all other Office 2007 updates as well.


I've heard of this issue on Office 2007 before.. Be sure to save documents frequently. In addition, if you're using "Paperport", try removing any Paperport COM add-ins from Word. There may be other add-ins which could cause the issue as well..

Hope this helps.
