Remarks

Beaucoup d'entre vous m'écrivent pour des problèmes d'ouverture de fichier (certificats expirés,fenêtre de sécurité java, fichiers geogebra. jar inaccessibles à partir du site Geogebra, etc,)A ce jour,j'ai remis en fonctionnement tous les fichiers en maths et sciences. Il ne me reste plus que ceux qui proviennent de l'ancien site Geogebra Upload Manager (ancien GeogebraTube laissé à l'abandon) qui ne sont plus opérationnels.Mais vous devez aussi de votre côté configurer votre sécurité Java (Voir ici le protocle) et accepter ensuite les avertissements de sécurité de java
