This is what happens when you try to solve something yourself with out consulting the board .....
I was trying to find another Office suite besides Libre and WPS so I downloaded FreeOffice 2021 and had a real problem getting it installed on my OS (and Cinnamon) finally got it installed and was setting it up when I tried to open a Libre file .... FO 2021 says it can open Libre files ....
When it did open I could not close the file either in the file or by clicking on the icon in the Task Bar .... it refused to close .... so I right clicked on the icon in the task bar and it said "do you want to delete" and of coarse I said yes .... well it deleted it alright it deleted all the icons on the left side of my Task Bar and when I open say Vivaldi it doesn't appear in the Task Bar so I can't save it .... only icons I have is Master menu and Show Desktop .....
