With IE7 and FF3 on a 1680 x 1050 monitor, I see no scroll bar. While the content centers, there is a grey strip running up and down the left, the colorful background not reaching all the way to the left.
On my 1024 X 768 monitor, content centers, colorful background background fills screen, but in IE7, the content is cut off just below the main content rectangle, the white text with address, etc, is not visible and no scroll bar available to see it. In FF3, even the bottom of the rectangle is cut off, again, with no scroll bar available.
Menus background image is smaller in width and height, not filling the screen vertically or reaching to the right.
I like the background color and will be looking forward to see how you resolve this.
How did you create the transitions for the background colors?
Best wishes,
