Hello . I was Working something on my computer last night and my younger brother aged 5 years was sitting beside me. My dad just called me for 5 minutes for some work and I went. As soon as I came back I saw my brother was just pressing any buttons on the key board and my screen was rotated in 90 degrees clockwise direction. I was shocked to see it as something like that had never happened before. How can I fix my problem? Is it a big problem? Please help. I am using windows XP.
