That behavior hasn't changed - anything not written to disk is obviously going to be lost if the server or webdna crashes regardless of any safe write feature. The problem addressed by safe writes is the corruption of a database file if the server crashes in the middle of writing out the database. Because the original database is saved as a backup until the updates are successfully written out, it can be recovered should the save fail. - brian ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
