It was only late that we were alerted that the navigation menu of our site was not displayed in the Safari browser (Apple hardware) . We therefore made a correction, alas, this one requiring to modify each page and, this site having a large number, we had to simplify by modifying only the home pages in each language. Safari users will therefore have to return to the home page each time to view the pages that interest them, by clicking on the header image. With our apologies for this inconvenience.
