Since a project opened then saved with Designer 2 cannot be opened with Designer 1, I decided it would be a good idea to archive a copy of my projects and patters to date. If for any reason I would need to go back to Designer 1, and I can think of a few, the projects would be available. Just thought I would pass this idea along. I don't recall seeing this as a suggestion. It might be something for LHR to consider advising Designer 2 customers.
