           Summary: Treeview refuses to sort
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-gui
        AssignedTo: wine-bugs at winehq.com
        ReportedBy: taviso at sdf.lonestar.org


using Kazaalite with builtin comctl32, if i try to sort a treeview by clicking
on a column title, wine wont sort it and prints this message

err:treeview:TREEVIEW_Sort invalid item hParent=0

as a temporary workaround, i changed the following in TREEVIEW_Sort() from
treeview.c

    /* Check for a valid handle to the parent item */
   if (!TREEVIEW_ValidItem(infoPtr, parent))
   {
        ERR("invalid item hParent=%x\n", (INT)parent);
        return FALSE;
   }

to 
    /* Check for a valid handle to the parent item */
   if (!TREEVIEW_ValidItem(infoPtr, parent))
   {
        ERR("invalid item hParent=%x\n", (INT)parent);
        /* return FALSE; */ /* i still requested a sort.... */
        parent=infoPtr->root;
   }

which does the trick for now, and all columns sort as you would expect.
