Ok...I will do it again.
The previous attempt did take forever and when finally prompted to enter my admin password, the "problem" prevented me.
How long do I need to hold down the "shift" key?
Do I need to tape it down while I do something else?
Can I stay in Safe Mode for however long it takes to assure the problem is or isn't occurring.
As I said previously, I did a lot of house clean, including deleting orphan files and apps that were abandoned and/or incompletely uninstalled....
I've had the computer since 2010 and there was a ton of miscellaneous stuff to trash.
That said, the computer is definitely behaving better.
Yesterday, at this time and place, I was gettin nauseous watching the desktop dancing.
Now, the window is more stable, although, on Facebook, earlier, my posts would slide to the right and off the screen, unprovoked, but FB would ask if I was done and allowed me to continue.
That's way better than the post deleting itself and FB saying: "Oops...something went wrong..."
It would be premature to say all is well, but it's definitely better.
I'll let you know how Safe Mode went.
