Unable to spy the objects desktop application

Hiya!

So, I'm not familiar with LibreOffice so I can't speak specifically to the application itself...but there in lies the issue.  Without familiarity with the application, I cannot say, for sure, what the solution for your problem is.  All I can do is make a guess.  So, here's my guess:

In your "data.png" file, what I see is that in Form("LibreOffice"), there's another component Client("LibreOffice").  That kind of speaks to me that what we're seeing inside the form is some sort of web client, web form, etc., that is being served up inside the form.  Like iFrames and other similar components, this may be masking the contents so that they aren't shown as individual components.  It would be as if I was trying to map control that are served up inside a Remote Desktop connection.  

I guess my first place to start would be to examine Client("LibreOffice") and determine what that actually is and see if there's a way I can use MSAA or some other leverage to get to the contents of that component.
