Aaghh!

I have been wrestling with my computer for the last couple of months. Libreoffice kept on crashing every time I pulled up my proof to do some edits. After trying everything I could think of, I eventually reinstalled the PC and as soon as I opened the file, it crashed again.

I eventually found that there was a hidden file in the directory with the suffix .loc. Once deleted, everything worked fine... I wish I had known that before I reinstalled the computer.
