The contextual menu in spanish is incompleted translated. In many cases the contextual menus are not as well as used to in previous versions.
[Reproducible] with "LibreOffice 3.5.2.2 - Windows XP SP3 (32bit) Spanish UI"
Thanks for bugreport Please, verify in 3.5.4 version. If not translated yet, then attach few screenshot of not translated menus.
Fixed for 3.6.
