i have open home, dxtop, ahome, and of course the htc home.. the problem im having is when i change the wallpaper on my htc home, all my other homes change too.. so i go to the next one ( lets say dx top) and change the wallpaper so it will be different from my htc home i chose, and it changes them all to what i selected for dxtop.. so i move on to the next one ( lets say open home) and repeat process and have tried in every way i know possible, even skins, and themes do the same, it just makes them all look the same, when i want them to look different.. help me out!!!
