TA 1.8c beta 1a: Foreign Relation Screen Black is Washed Out

This is ridiculously trivial and, I believe, was also present in beta 1. But most of the black backgrounds in the Foreign Relations screen (F5) are washed out. I haven't noticed this with any of the other black objects/screens in the game. This is a Terran/Medium map/Everything abundant/Tough game in TA 1.8c beta 1a under Vista Ultimate (x86) using an NVIDIA 7600GT graphics card.
