Put jvDockNewStyle in the {jedivcldir}\run and open up 
jvDockingReg.Pas which is the design folder of the jvcl
directory.  

Add:
jvDockNewStyle

to the uses part.


Add
, TJvDockNewStyle

Right after TJvDockVSNetStyle. 



Then recompile jvcl and it should install.  I switched the delphi style to show
the new style in the advanced demo and included it in exe so you can descide if
you wish to even install this.  Up to you.  Enjoy :)
