Error (RT) in __ToolsControl._WinList

[ScottF]

Hi Gintaras,
I am getting RT Error trying to get Accessible object from a "LibreOffice Calc" window,
using the Accessible object Dialog. Was taking long time to fail.

The error:
 Error (RT) in <open ":4211: /676">__ToolsControl._WinList:  window not found (the handle is invalid).    <help #IDP_ERR>?

__ToolsControl._WinList:
Line #26     s.getwintext(h); if(!s.len) s.getwinclass(h); s-"+"

QM Version 2.4.12.0   
Windows 10 Home Version   20H2 (OS Build 19042.867)

Any other way to get AO with Libre?

Scott
