ListView control on Tab and WM_NOTIFY Event error + reproduction.

[Shlomikalfa@…]

[Description]

I have a listview obj, created using the built-in inside a TAB at the 2nd TAB.
the items are inserted using a _UDF someone has donated in the forum...
it is being monitored by WM_Notify [just like in the help file].
when i click on entry #3, Row #4 of the listview, the TAB always switches to it's first TAB item.

[Reproduction]
#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>
#include <WindowsConstants.au3>
Opt("GUIOnEventMode", 1)

;$Debug_LV = False ; Check ClassName being passed to ListView functions, set to True and use a handle to another control to see it work

;;;>> Doesn't create the listview on the tab required but for entire $GUI. [However, if this is used the issue is gone, maybe because of the Listview location...]

MyGUICtrlCreateListViewItem($i&"|BLAA|ASDA|ASDASD|ASDASD|ASDASD|ASDASD", $hListView)
;;; USING THIS FUNCTION >>
;;; because of _UDF lack of ability to support unicode properly.
;;; because of built-in flickering property, [it just flashes like a milion times during the updates].
