hello there! we’re using version of LO 7.4.3.2 and i don’t know since when but LO allow user to open already editing doc,
how it was before (as you can see there is only option to open is read only)
but now it allows to open already opened document, 'cause there is this button “Open” right in the dialog box
mine questions here is why does LO allows to open document that already in use
