Two of my users get the following message fairly frequently when they are in the main data entry/update form of my database, either upon closing or when trying to update information:<br><br>*******************<br>'frmFormName' has been changed since the last time you opened it, either by another user or because another instance of it was opened on your own machine.<br><br>Do you want to replace the changes that you or another user made?<br><br>To save your most recent changes and discard the other user's changes or your previous changes, click Yes.<br>To save this version of the object with another name, click No.<br>************<br><br>The users are definitely not changing the form (by going into design mode).<br><br>Does anyone know what might be causing this error? I can't duplicate it, but it happens frequently to people who use the database a lot. Is it something the users are doing? Something my VBA code is doing? Or a corruption of the database?<br><br>Any ideas would be helpful. Thanks.<br><br>
