Total Commander

I've noticed in the Help that the buttons on the Button Bar are shown as having colors, but in my TC4A they are black-and-white - both the stock buttons and the ones I've added. Is this how they're supposed to be? Icons in the File Lists have colors.

It's not a problem if that's how they're intended to be, I just thought maybe I've got a setting wrong or something like that.

Yes, it's intended to fit the newer default buttons. You can revert to the older TC icons in the configuration - Font and Colors: Uncheck "Use new icons".
