Wallpaper not changing properly in WindowBlinds...

Here is my info.  Figured I would put it in since most threads are asking the creators for it.

I just purchased this yesterday so please bear with me.  When I apply a visual style, everything changes fine except the wallpaper.  I understand that some themes do not have this included.  So, I go to the wallpapers tab to change it.  I choose my wallpaper from the folders that I have added to it to search in and maybe 1 time out of 10 it will change it properly.  Other times I will just get a solid color background.  The color is different most of the times but it is always solid.  Please advise.

Thanks in advance, Roy
