Well, when you put the mouse over calendar control, in a given day, a tooltip came saying "click for day view, right click for more.." or so, and you supose to translate that string but that never happen. I have tried this both german and french locale and neither works. Also when you right click over the same calendar control, it says in a context menu "add task for..." and "change to day view, chamge to week view.." and I translate that string in the locale and never shows up the translations. But if I translate monday, tuesday, etc, and january, february, etc, it works. Also, the months and days works for the main calendar control, but not if youre setting up a new appointment, in such a case its in english the months and days.
