Yesterday I upgraded Libre Office to the version 6.2.0.3. After this operation in files which were created in former version and saved as .xls the hyperlinks to internet don’t work. After clicking the cell +ctrl I have got the information that the page is not found. If I copy the content of the cell and paste it to the browser the page is found.
Tested on my own system with creating .xls containing hyperlinks and using 6.1.5.2 and open with version 6.2.0.3 and cannot confirm (my links do open) - so I need to assume, that any help effort will require a sample document of your non-workng xls files.
