Hi, I'm running Calibre 6.19.1 in a Linux Mint 21.3 Cinnamon system.
I also use LibreOffice, which saves files in the .docx format.
I want LibreOffice to be the default application for opening .docx files, but unfortunately Calibre somehow gets set as the default application for opening .docx files instead.
I have tried setting LibreOffice as the default, and I have told the file manager to forget the association with Calibre (see image). That seems successful, but then later I find Calibre listed as the default again.
Is there some way I can instruct Calibre to exclude .docx files?
