It seems like it is almost the same problem that I ran into(see my other thread) except that I wasn't getting any error messages. The computer would just freeze. I googled "computer freezes on MS Word and found some really good info which fixed my problem. There are also three other files in Word that can get corrupted. They are: MSo9intl.dll, MSohelp.exe and MSoffice.exe. The recommend procedure is to find these files and change their extensions to .old, then re-install Office and select "repair". This might work.
