When you change a theme do a battery pull.I pull everytime I change anything on BB as a matter of course.If it is still messed up after that,it is probablly problems within the theme itself.Try another if that is the case.If you like the icon set of a theme but not the wallpaper,just find a wallpaper to replace it.There are alot of free & paid themes here at crackberry and many free wallpapers.
