Listbox click item not working if list box off screen

[woodpecker 0]

Hi folks,

I am trying to click a listbox item in an application which is in a scrollable panel and may not always be in the visible part of the panel, _GUICtrlListBox_ClickItem($hWnd,$index) works fine when the listbox is scrolled to be visible, however when the listbox is scrolled out of the visible area it won't work, I've also tried _GUICtrlListBox_SetCurSel($hWnd,$index) which didn't work, any idea how to accomplish this please?

Is the application publicly available? We are probably gonna need to know what it is to help.
