Changing tab name lead to items disappear

[ReDFlaG]

Hello all,

When i change the name of a tab, the items that are holded into the tab disappear.

i've found a workaround but it makes the GUI flicker: GUISetState(@SW_HIDE) then GUISetState(@SW_SHOW)

Is there a clean way to do solve this issue ?

Thanks

Here 's an example of the issue:

#include <Constants.au3>
#include <Array.au3>
#include <GuiTab.au3>

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

$mainwindow=GUICreate ('test',850,750,-1,-1,$WS_SIZEBOX+$WS_SYSMENU)

$hTab = GUICtrlCreateTab(5, 10,800, 700)
GUISetState()

$Tab1= GUICtrlCreateTabItem("TAB ")
GUICtrlCreateCheckbox("#",20,50,70,50)
GUICtrlCreateCheckbox("#",20,100,70,50)
GUICtrlCreateCheckbox("#",20,150,70,50)
GUICtrlCreateCheckbox("#",20,200,70,50)
GUICtrlCreateTabItem("")

sleep(5000)
 _GUICtrlTab_SetItemText($hTab,0,"CHANGED")

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE
GUIDelete()
