Belay my last...it appears we have changed cursor themes. I discovered it when I launched Nautilus again. The 'busy' cursor was indeed different, and from that point, the pointer was also...and it is now larger.
When I restart Cinnamon, or restart the computer, the original default pointer is present, but when I start using the system, the new ones come into effect.
Thanks, Oscar....this one appears to be solved.
