Ok thanks for you reply
Too bad not to have the choice (the hand) on the modifications made by SAB (we did not make any modifications on the hard disks design or something related in SAB)
We didn't even know SAB had an impact on this
For aero.msstyles, some settings are modified with the registry, which does not work with a theme name modified (xxxxx.msstyles)
The registry applying the changes only on aero.msstyles it would seem (color of inactive title bar, eg)
Nevermind, we will stay with 3.5.7 which does not affect this design and see what to do when 3.5.7 will no longer support new versions of Windows
Or if we find how to change this in the theme but not yet found
EDIT : Or if it's possible with SAB to have color in inactive title bar (same as active title tbar),
But I don't think, it's already not possible to have options of ONE
