I run Vista on my Macbook. It's a great machine, but some of the drivers are flaky, because they were intended for XP. Until Apple updates Boot Camp for Vista, you must use the XP drivers.
Today, I noticed a Windows Update for the chipset drivers. I was feeling bold, so I let it install. I hadn't noticed a difference until a few moments ago while surfing a web page. I wanted to return to the top of the page, so I pressed "fn+ctrl+left arrow" (which is the equivalent of ctrl+home), or so I thought.
Actually, I pressed "ctrl+alt+left arrow" and my display rotated 90 degrees to the right! I realized what I had done, and tried "ctrl+alt+right arrow" to remedy the situation. That put the display 90 degrees rotated to the right. Finally, I tried "ctrl+alt+up arrow" and the screen returned to normal. Can you guess what I tried next?
