Features / Usability

 Thank you artsegura for specifying your problem,

that points us to s different direction.

I roughly remember that there have been issues with MS files and that there are solutions. I do not remember, as I usually have no problems with 'em.

Maybe Rick has an idea, otherwise I think about and come back once I remember what it was ... you might be finding something in the forums. Maybe search for xlsx or so.

Regards,
Torsten
