OK Ron!

Have you actually - successfully - used the "Make box set" instruction from the "Tools" menu at any time? If so, there must be a "Box Set" tab in the entry's properties. The only other possibility - as you have hinted - is that this tab only came in with a newer version.

So.... is there any reason for not downloading and installing the latest release? I have never had any problems doing this and simply running the new install file over the top of my existing version. No data has ben lost or corrupted. Sure, it will open with the new default template/theme, but you can change this back to your preferred theme easily enough (via the "View - Preferences -Theme" tab).

It might be advisable to do a back-up copy of your database first, if you are worried about losing aything! Just copy it and keep it - temporarily - in a different location. Or set a Windows restore point before installing. Am I helping at all?!! Hope so...
