I'm not positive it will help in your case, Frank, but you might try the Project Utilities/Project/Check ...Pack and Repair options. This removes records that have been deleted from the project or library. But it also packs, and rebuilds index files associated with the project, (which,I believe, will remove unused numbers), and optimizes the project and library files. Make sure to read the information in your manual. Version 2.7 is an early version and there has been much updated since that time. If you are looking to upgrade at all, I would highly suggest TMG.http://www.whollygenes.com/ It is a smooth transfer from UFT programs from what I understand and, the more I see of it, the better it looks!
