Is there a MANUAL wallpaper switcher for windows vista out there? i do not care whether it is an individual program or a vista gadget. either one would be okay. Every one I’ve come across changes the wallpapers at intervals of certain times. For instance a vista gadget that lets me change between wallpapers with a single click would be great. Thank you.
