sigh.... well, I will have to live with it for now. I have my limits when doing stuff on computers.

I think I'll get my son over here and see what he says. He has been uploading the computers at work for Win10 and is thinking of doing his roommate's, but hasn't done that one yet. Soon he should have a handle on some of this stuff. He has an Apple himself.

I also have a scroll bar now on this program at the bottom of the page. I don't recall seeing this before. It disappears if I ctr+scroll wheel to the smallest size--which is so teensy no one could read it.

Kiwi... the actual download is pretty easy, but does take some time. The speed of your processor determines the install time. ave 1-2 hrs.
But learning to live with it and/or modify it to suit your needs appears to be the frustrating part of it all, at least for us. I did not lose anything. But hubby lost his start up graphic on his laptop. He fiddled with settings too soon before he understood things, and lost his tool bar.
And I have my "mystery" music icons on my media player. For some reason my graphics program had to be uninstalled and reinstalled. But my 2 Angry Birds programs remained active for me. Overall the computer seems to run better, subtle improvements in resolution of images, and the music is clearer. The vertical scroll bar doesn't flip/stutter anymore and seems very smooth.
