W7 Style Builder - window corner glow

Hi, I can't seem where to find the image/setting that controls the subtle white glow at the top left/right corners of windows in W7 Style Builder. Other themes have been able to disable this and it would be appreciated if someone could point me in the right direction (I'm not trying to remove the glow, but rather 'copy' the glow and add it to a theme that doesn't have it)

For a screenshot of what I'm talking about: (see how the top corners are slightly whiter - this greatly helps with reading titlebar text on dark backgrounds, which is why I don't understand why so many theme authors remove it)

Go to Windows and Caption Buttons > Aero > Dwm Window > Reflections and delete the color (it is very lightly colored) with a image editor of the three areas highlighted below.
