Thank you and the rest for some good stuff! It's residing on my machine.
StarFerret's lappy's updating to Build 14251 and I'll give it to her when it finishes.
I've seen something similar on Windows 8 once. Did't give much attention to it but I can't reproduce it now.
Have you switched to AeroLite.msstyles theme or Aero.msstyles ?
If you switch from HighContrast, which is also uses AeroLite.msstyles, to an AeroLite theme it is possible to see a color glitch where not all colors switch.
