The backgrond image for the Shredmania window options is all blacked out.
It is a transparent gif. the DIV contains a small checkbox form. Some style
properties --background image-- define the div. This stylesheet is in the
head.

I want to know why the image is all black and what to do about it.

Another problem here is NN doesn't launch the window! Bad form over bad function,
I guess.
