In my particular case the
issue noted in the original post, Port/Channel section blank,
has been fixed in
Sonar Platinum Everett Update #1. From what I can tell it may have been something overlooked in Everett 64 bit version. Thanks to all for your rapid support, especially the omniscient Mudgel.
Maybe we could call it "X4e", or would that be too easy!!
Cheers,
