TreeView & WM_NOTIFY

It looks like comctl32.dll is seting up some hooks to forward messages
to requested window because even if you use --dll comctl32=n the owner
is set up to "GetAncestor( cs->hwndParent, GA_ROOT )" Same thing
happends under Windows so it seems that everything is OK with
I tried to figure out what is going on with hooks but I don't have much
experience with windows hooks so I will appreciate any help.
