I was asked a question and I had no idea what the answer was and made up some story about information being stored incorrectly in the memory of the laptop or some such thing. Honestly, I had no idea what the answer was, so I'm hoping someone here does.
Often times, while running windows, the desktop icons or the desktop will go black. When you mouse over where the icons are supposed to be, they appear, and the desktop appears while moving the mouse as if it's being painted. What causes that? Is it the the windows cache, physical memory, or something else?
