How to change background/text color in reader9?

I just switched from vista to win7, and thus did a fresh installation of reader 9. I forgot what version of reader I was using under vista. In that version, there's a feature that I like the most, the ability to change the display document's background color and text color. I usually use a black background with white text, which I find is more comfort than the default white background with black text. However, in this newest reader 9.2, I can't find the option to change those colors under preference tap. So does 9.2 still support this feature? Or I need to use an older one if I want to change the color? Thanks.
