Hi Everyone, I was wondering if anybody has some thoughts on this subject. Recently I installed xp64 and it works beautifully except for one thing, whenever the mouse moves over a window or application that window gets switched to automatically. For example, say there are two windows open, one on top of the other but you can still see the window behind it because they are not directly on top of each other, if the mouse moves over the window that is behind the one being worked in the computer will automatically switch to it. It seems like preference error or maybe a registry error, I have looked at all windows utilities and administrator settings and can not find a way to disable it. Any thoughts or fixes are welcomed and will be greatly appreciated with 50 bits of gold. thanks so much.
