Can not close GUI when function is executing

[kazuoscripter]

While 1
      $nMsg = GUIGetMsg()
      Switch $nMsg
         Case $GUI_EVENT_CLOSE
            SaveSettings()
            GUIDelete()
            Exit
         Case $Button2
            SaveSettings()
            GUIDelete($GUI)
            status()
            checkstatus()
      EndSwitch
   WEnd

This is my GUI script, when i click $Button2 to delete GUI1 and open GUI2, its starting checkstatus(), when its running i cannot close by click X button on top right GUI2 (status())
Thank you!!
