Thanks Amadis for settling that, even tho such a long time ago.
You know there are so many queries out there abut this issue and most of the replies have simply not understood the question: by "default setting of navigation page" we did not mean whether it is on the LH side of the page or not, nor any other of the weird things people have replied to, meaninglessly: we meant, how we can do a word or phrase Search in a document without getting this absurd "Navigation Pane" starting us off with the irrelevant "headings" rather than "results", which is what used to happen automatically before some update.
