As a matter of record, I post now the results of following the instructions for bible position in parallel viewing. To keep the experiment simple, I removed all bibles from the module folder except AV1769, Geneva, Bishops, Tyndale. Without name changes they appeared in the parallel viewer in the order of – AV with duplicate verses, Bishops, Tyndale, Geneva, AV with no entries. Thus, it appears that the entries for the second AV transferred to the first AV, creating the duplicate entries.
On renaming the bibles, (1-tyndale.bib, 2-geneva.bib, 3-bishops), they appeared in the order of – AV with duplicate verses , Tyndale, Geneva, AV with no entries, Bishops with no entries.
Recall, I am a Unbuntu 10.04 user; so maybe, Linux has something to do with how things came out. However, I can do my study just fine with the original parallel display: so it does not matter.
For what it is worth, I think there should be a paragraph in the software somewhere indicating the basis of the preference for the AV1769, stipulation of what the other AV is, and notation of which AV is whatever as they appear in display.
Thanks for the help in increasing my knowledge and ability with the software.
