I was ecstatic to download the iPad 4.2 operating system today. Mainly because I've been waiting to be able to create folders for my bookmarks. I now have my seven pages down to one and a half- Woo Hoo!
BUT.... ( insert imposing DUM DUM DUM music...)
They changed the screen lock button to a mute button! ARGGH! I was perfectly fine with toggling down the volume switch to mute. It was bad enough trying to read a website with the screen changing orientation on me, but I could only imagine how frustrated I was going to be trying to draw on this thing now.
So, I did some googling and found a solution, which I've shown in the screen capture above ( yes that is me and my beautiful girls and our dog on the screen). To lock the screen orientation, double-click the Home button on the iPad and slide the gray tray all the way to the right to reveal a lock, volume, and brightness controls and iPod playback controls. Yay! Crisis averted!
