I learned one this week the hard way. While trying to get one of the programs to close out, I did the Ctrl, Alt, delete a few times, or so I thought. To my dismay, the computer screen totally flipped 90 degrees and so did the mouse arrow. OK, what the heck did I do now?? I was too tired to do anything about it, so I just shut off the computer.
The next day, craning my neck to Google the problem with everything akimbo, I discovered that all I had to do was Ctrl, Alt and Up arrow, and it flipped right back.
I guess I inadvertently did that the night before instead of Ctrl, Alt, delete.
Hensylee, I tried the mouse wheel thing, it didn't work on my computer, unfortunately. Sounds like a good thing.
