I changed the color scheme of the tool windows to match VS 2012, and it worked correctly for a week or so. Starting today, the colors always revert to standard for the Tests and Coverage tool windows. The configuration tool windows displays the correct settings and interestingly has also the correct colors. If I change the colors in the configuration just a bit, the tool windows then pick up the correct color change.

Every time I quit and restart VS 2012, the Tests and Coverage windows revert back to default colors again and the Configuration window has the correct colors in the settings and is also displaying with the correct colors.

This is only a minor annoyance as I have one bright screen with the NCRUNCH data and the rest is dark. Anyone with the same problem?

Thank you for your very quick response. It turns out it's a "user" error. I cleaned my source code folders and that disabled NCrunch for the project. I did not have to run tests until just now. Enabling NCrunch fixes the issue instantly. I'd say not a bug.
