Just spotted the update on Impulse:
-Added advanced glass support including new sections for SkinStudio - sweet! full feature-parity with msstyle hackers at last!
-Improved compatibility with pre-release Firefox 4 and IE9 builds - nice bonus
-Added new IE9 sections
-Added support for per-skin custom colors
-Optimized skin changing speed on 64-bit Windows
-Fix for occasional multiple wbvista.exe error
Thank you Stardock! This could be enough to give WB its mojo back
