Then what is the point of Windowblinds. All the tool bars (etc) look horible without a wallpaper. Wincustomize should indicate which ones have a wallpaper or star dock should refund my money for worthless software!!!
Err..... I see you've totally missed the point about WindowBlinds.
WindowBlinds isn't a wallpaper changer/manager. It's a GUI changer with the possibility for changing wallpaper as well.
It's all up to the creator of each theme wether he/she wants to include a wallpaper, not the software developer (Stardock).
