Thanks, I got it ! I've added a "RikMenuBarTransparency" key in RikInfo.plist, 
and now I can override it when I write in NSGlobalDomain as you explained.  I 
also cleaned up a little this plist. I've still got an issue with it : the 
"GSBackendHandleWindowDecorations = NO" that it contains doesn't seem to work 
(I've looked in the other domains if it is overridden and it isn't). I still 
have to investigate, but I did understand a few more things today.
