Microsoft has posted a bug fix for Word 97 (also known as Word 8.0) to its Web site. The bug caused documents that have been "Saved As" to lose information. The update overwrites two Word 97 files. For more information, check out the Microsoft KnowledgeBase Article "WD97: Save As Command Does Not Close the Previous Document".
I was unable to locate this bug-fix (named "ODMAupd.exe") anywhere online at the time of this writing, unfortunately. I will post this information when it does becomes available
