Prevention
Microsoft recommends turning off the Auto-save function in Word. Note however, this is a prevention and will not repair equations that have already become non-editable pictures. The steps to disable auto-save are different for each version of Word whether on the Macintosh or on the Windows platforms. Simply look for the "Save" preferences for your version of Word and remove the check mark from "Save Auto-recovery data every x minutes."
