Here is a small patch for the ZCS-5.0.6 French translation.
The patch corrects some minor contextual errors in the user interface, and installs the French spelling dictionary and the French date zimlet.
The problem with buttons labels displacing the Prev/Next arrows out of the window in small displays has been fixed (thank you Zimbra team ;-), as well as some of the labels modified with my patch in 5.0.5.
As usual, you can get the file from Fichiers WHM (user invite, password invite).
Otherwise a ZIP file with the patch is attached.
