I opened "keyboard preferences" and in the "layouts" tab i added Greek, after English us. Then in the panel i added utility-->keyboard indicator. A box appeared with the indication us. When i clicked on it, it changed to Grc (probably Greek), but when i tried to write anything it changed back to English and instead of Greek i wrote English. When i opened "keyboard preferences" and i pressed the button "up", Greek moved up, but exactly the opposite happened. When i changed the indicator and tried to write English, the indicator changed back to Greek and i wrote Greek instead of English. What can i do?
