I have a problem to navigate in french help file (5.0.9 open source edition).
zimbra/help/fr/advanced/Zimbra_User_Help.htm is displayed correctly,
but when trying to access an item from the main menu (, nothing happen.

When using "Index" it works fine, but not when using "Contents".

I made another test using the english help file : works perfectly.
I made another test whith spanish : same problem as french.
