Neo -
I don't believe that section will allow you to selectively change the color of just the status bar - that color defaults to the button face color (3D objects in Display Properties) for unskinned windows - the status bar is almost always skinned, however. I'm pretty sure the colors that subdialog refers to are the ones set in the Classic Colors section of SkinStudio & apply only to unskinned windows, although it appears to also allow you to change some of the skin colors (text, text shadows, etc.).
If INVI does not skin the status bar, then changing the button face color will change the color of the status bar. Will also change the color of unskinned buttons, obviously, as well.
