奇怪...

There's sth. wrong with my T43 dock extension today. IT engineer helped to to do some tests. The problem is I didn't put it tight. Any way, it is good now. A strange thing happened, that during testing my T43 connection with dock, when I turn off my display then turn on, my wallpaper has been changed to my previous one, which I was using about two months ago. How could that be?
