ignore/delete this post
I am unsure why but I tried moving a few icons around about 30 minutes ago and none of them would move-they all floated back to their original positions on the primary display.
I just tried again immediately after posting this and it was working again.
That was REALLY strange.
My system is fast. NOT the fastest anymore but still fast with LOT’s a resources.
I guess I just need to keep an eye on it.
