Since you mentioned this, I thought it was important. You mentioned it again, so I think I got it right. The intent here was not to avoid your original complaint, but to eliminate a concern while diagnosing the problem. That may take time because only you can see and hear what your machine is doing. We may have to ask lots of questions so we can understand what is happening too.
I think the best path here is to upload the Lightburn (.LBRN2) file that is a problem so others can examine and/or test it to see if we get the same results.
