@ "Kolos So, now I can open directly from File manager and email client doc, docx, odp, ods, odt, pps, ppt, pptx and xlsx files".

Hi Guys,
I suddenly also noticed today that the file association of freoffice appeared in the file manager. Can open also the e-mail attachement.
Have still dBus-switchboard installed which let me via easy-debian (ooffice) open the doc , xls and ppt e-mail attachements before the freoffice file association appeared. The system now prefers freoffice opening the attachements and saved files instead of ooffice
Don't know what is happening!!
