I have not heard of this before. Snow Leopard will give a color to the gamut projection on the base of the 3D grapher that is the same color as the “single color” that you choose, and will give a multicolor projection outline when you choose “true color”. I’ve never heard of this not working.
I assume this happens with any profile you try?
When does the “CSerror: -43” show up?
It would be great if you could send us a screen shot of what you’re describing, and any pertinent hardware information. If you go to Web > Feature Requests / Bug Reports, this will give you an email so you can send it to us.
