Win7X64 Beta 2
The hidden & docked toolbar windows are locked to a black font that doesn't appear with a dark theme I'm using. The highlight buttons of the hidden windows are conforming to my windows settings (highlights are light blue, disabled is a dark button) and all other document tabs work fine as well - It's just these tabs. I set the 3D background to a lighter gray and in the 2nd screenshot and you can see the text is being drawn properly - Just not the right color. There's an option to configure the colors for the other document tabs but not, apparently, this one. Although I'd be happy if we could just get the docked and hidden tool window text to use the same color the other document tabs do.
