While trieng to get the hh program to work under wine I found that when 
I tryed to expand the Treeview control only the + become a minus (-) and 
nothing else happened.  Taking a closer look at some +message traces I 
found the following differences between the messages coming from the 
native comctrl and the builtin one: Both were sending the WM_LBUTTONDOWN 
message to their parents which is a Tab control.  The native common 
controlls was forweding this message to its parent and then the parent 
was adding the other items bellow it but the builtin one was simply 
calling DefWindowProcA and as a result the items werent getting added to 
the Treeview.  After replacing this statement with 
SendMessageA(GetParent(hwnd), uMsg, wParam, lParam) the Treeview control 
works properly.

Changelog:
  * dlls/comctrl/tab.c
     Pass on all unhandeled messages to the owner.
