@centrox,
Thanks a lot for clearing it up, good work, no kidding. I was quite confused, then started to call that square an emoji... which was more confusing.
No OS updating for me; Apple cut a lot of us off about six years ago, ex-ing out a variety of available applications over time (bye! so long!) and I can't spring for a new or recent used mac. That's possible in the future though.
Besides, I've had my own odd fun keeping an antique mac working at all.
Good a2k folks have suggested relatively inexpensive microsoft type computers, which I worked with in the distant past, but I'm not interested in relearning that system, and while they are less expensive than macs, I can't afford them either.
All is not lost as I have stuff to sell, just have to figure how to do it (long story I won't go into).
