Okay, we all know every window has a live preview, whether it's static or a moving picture or something similar under Windows Vista. I have Vista Ultimate build 6000 and every time I minimize Media Player, it does not display the live preview for the visualizations. If it's a movie it's working okay, whether it's minimized or not. I have installed the driver for my video card (the most recent ones, betas and non betas) and it doesn't seem to solve the problem. What can it be?
