I used the libreoffice spreadsheet application to create a file. I saved the file in odt format. I can now no longer open the file with libreoffice.
When I attempt to open it, I get an error message indicating that an unknown user has locked the file.
I am then given a choice to open the file in read only mode, which is pointless to me because I want to edit the file.
How can access the file from libreoffice, and prevent the files from being locked?
