I have a lady who use to send out "complex" .docx files, via email, to people in a transportation advisory group. I had a long "talk" with her, via emails, about the "incompatibilities" of MSO with their older versions. Now, most times, she sends the documents that are not to be edited as PDF files. The others she remembers about half of the time to send the files out as .doc instead of .docx.
She has changed jobs, promotion [sort of], to the department that oversees the company that she worked for. That department is part of the "County" government administration. I have been trying, on and off, to get the County to use LO in some of their areas of agency support that would be perfect for LO as a MSO replacement even using MSO document formats. I am working on the idea of saving money on their budget.
So the issue of the incompatibilities between various versions of MSO is part of the problem with buying new MSO packages, or "renting them". If I could get them to stick with an earlier version of the .docx file format or the .doc format, then that would solve some of their problems and would make LO perfect for some of their system needs/usage. They oversee several community computer centers. So getting the County on board will make it easier to get LO into some of the region's computer centers.
