Ok. Funny story. I tried Alt+0169 on Finale Notepad. It didn't work. I tried Ctr+Alt+C. Didn't work. I tried Ctr+Alt+0169. My entire monitor rotated 90
o to the right. I was
scared to death. My mouse moved funny and I couldn't read anything without turning my head sideways. I restarted the computer in hopes that it'd go away.
It didn't.
So, I randomly right-clicked. "Graphics Options" appeared. So, I clicked on that. "Rotate" came up. I clicked on that.
Normal
90
o to the left
90
o to the right
Those were my options. It took me awhile, but I finally got it figured out.

You can guess which one I did.
