With window sized so page requires vertical scrolling, the div background image scrolls up white rather than using the color of the background image. This problem occurs with Firefox latest public release on Mac OS X and on Windows XP. 

Reproducible: Always

Steps to Reproduce:
1.Go to http://booksworthknowing.geenius.com/
2.Size window to require vertical scrolling
3.Scroll page up - note the white fill.
Actual Results:  
White fill rather than using the background image to create the fill.

Expected Results:  
As window scrolls up expect the background image to fill in the background.

Of note IE8 scrolls properly filling in div background image.
