Every once in a while when I leave an app and go back to my desktop some of my icons have been moved. Because of my wallpaper I have arranged them in a certain way. (grouped together by type of app.(games in one corner, accessories in another...etc.))
There is no pattern to this at all, sometimes it happens after playing a game, sometimes when I leave the net.
Is this something I should be worried about, or just re-arrange them, and accept it?
