Thanks. I just found that that method does indeed work. But I also found that documents would open ok if I changed the view of the initial window with docs, music etc in it. It opens by default with a list. If I change it so that I have folders going across the page, rather than the list that is horizontal down the page, then things like text files open with a tap.
I’ll have to attack this later. Things like employment call. A linux task awaits tomorrow. Love these challenges (when I’m in the mood…and not say, in a hurry)!
