Once again many thanks for your effort, but I had the same result again, which means that the file is OK, but that either SU or my machine has a bug in relation to SU.
The interesting thing is that the results are always different with different lines missing at different times.
As usual you guys at this community rock. I don't know why this SU community has always stood out so much from other forums. I don't know but it has always been such a tight and friendly bunch all the way back to when I started with SU which was version 2.1. At least 8 years back. I never was a great contributor, but in my active days I was following this forum religiously.
Keep it up folks
