method
Product: LibreOffice

Description:
I'm building a C# library to control LibreOffice that you can find here -->
https://github.com/Sicos1977/LibreOfficeKit
All build work was done and I was in the stage of testing it with all diferent
kind of documents. It all works fine with Microsoft Word like docs (.doc,
.docx, .rtf, .txt, etc...)
But as soon as I touch Excel or PowerPoint kind of files the loading hangs on
line 684 in the Instance.cs class. I added event callbacks to see what
LibreOffice is doing.
