Thanks - I was really hoping to be able to only change the explorer background. Problem is, as is well known, if I use Windowblinds (on Win 8.1) to change the frame, then I lose anything added - like icons from Filebox extender (which may disappear or be distorted or mispositioned) and right click options as from PowerMenu.
With Aeroglass I have transparency; I can have a rounded Win 7 like theme; I can set the window background (bar explorer, control panel...) to a pale yellow on most other things - and not lose it after resuming from hibernation, despite MS having so thoughtfully taken away the Appearance and Settings GUI - which just leaves explorer (almost white) for the most part.
So the old settings here appeared to allow very selective application of a skin, and that interested me.
