Thank you, Blake
I went back to get a copy as you suggested and now it isn't doing that anymore. I regenerated it several times and the chords were all good. It may have been related to another problem I was having which was an Access of violation error which was caused by a duplicate bbw.exe which I fixed today and then re-loaded my BIAB, Maybe it was a fresh reload that I needed to do last night. Anyway things seemed to have straightened themselves out. Maybe it was just a "quirk" that may never happen again. I hope so, but if it should ever happen again I will do what you suggested.
In the many years that I have been using BIAB the staff there have always been so helpful whenever I had a problem and I really do appreciate it! Thanks again to all of you. You're doing a great job.
