Hi I was working with Word 2004 today on my Macbook Pro 15" and went to save to my HD. I got a message saying there was a problem writing to "Macintosh HD" because it was full. It said to shut down other programs and windows. In Word, it wouldn't let me save, save as (renaming), and even auto-recover save would not work. I restarted and the error message has not appeared since. My HD is NOT full. It says I have ~92 GB free. My Office 2004 software is up to date. Any ideas on why this happened? Thanks for the help.
