Sorry, hit send on the last without saying anything...

This seems to be a bug in the TabControl code in the common controls DLL.
It doesn't like getting the LVN_DELETEALLITEMS notification, which it gets
just before a child listview item is destroyed.  In SubProc, you can add the
following right before the call to the tab control's default window proc
(which I've included here):

if window_type[id] = TabControl and iMsg = WM_NOTIFY then

    VOID = fetch( lParam, NMHDR_code )
    if VOID = LVN_DELETEALLITEMS then
        return popSelf()
    end if
end if
returnValue( w32Func( xCallWindowProc, { window_func[id], hWnd, iMsg,
wParam, lParam } ))
