My minor annoyance is that my Desktop Background photo changes from “Fill” or “Stretch” to “Center.” This is an ongoing problem. If I go thru Customize and reset it to Fill after a while it goes back to Center. I have tried a variety of photos and all seem to do it. I’m using a Gateway Laptop NV series, 17-inch display, 64-bit, screen resolution 1600x900 (recommended). Windows 7 Home.
