Deepak was sitting on my lap, when I was checking my emails. He was watching songs in parallel.
He started to press keys in keyboard and my screen display got turned up upside down. Mouse cursor would also turn down and movement was the opposite.
It took some time for me to get mouse control in reverse direction and find cause for it.
ctrl alt up arrow shortcut with XP has done the job. I had used the UP arrow when he had pressed ctrl and alt simultaneously.
Pressing the ctrl alt up arrow again got the screen back to its position.
